admiral (development version)

New Features

  • New function derive_vars_cat() for deriving pairs of variables or more, e.g. AVALCATx & AVALCAxN. (#2480)

  • New function derive_vars_crit_flag() for deriving criterion flag variables (CRITy, CRITyFL, CRITyFLN). (#2468)

  • Replace use of data("sdtm") with sdtm <- pharmaverse::sdtm in templates and vignettes. (#2498)

  • Remove dthcaus_source() calls in ADSL template because they are deprecated. (#2517)

  • Update ADEG template to flag ABLFL and ANL01FL based on DTYPE == "AVERAGE" records. (#2561)

Updates of Existing Functions

  • NCICTCAEv5 grading criteria (atoxgr_criteria_ctcv5):

    • fix for TERM = "INR increased", criteria was wrongly using x ULN, for first part of criteria for grades 1 to 3. For example, ">2.5 x ULN" changed to ">2.5" for grade 3. (#2534).
    • when looking at abnormal baseline we now use BNRIND instead of comparing BASE with ANRHI, as ANRHI may differ within a subject and lab test due to data from different lab vendors. This effects 5 terms, namely, Alanine aminotransferase increased, Alkaline phosphatase increased, Aspartate aminotransferase increased, Blood bilirubin increased and GGT Increased. (#249)
    • derive_var_atoxgr_dir(): new argument abnormal_indicator to pass in value of BNRIND to indicate lab test is abnormal. This is only used for the 5 lab tests described above. (#249)

  • The keep_nas argument of derive_param_computed() was enhanced such that it is now possible to specify a list of variables for which NAs are acceptable. I.e., records are added even if some of the specified variables are NA. (#2510)

  • derive_param_tte() now provides a useful error message if in event_conditions or censor_conditions a dataset is referenced which is not specified in source_datasets. (#2519)

  • The derive_param_qtc() function accepts now both "ms" and "msec" as unit of the input parameters. (#2513)

  • In derive_vars_query() the error message was improved for the cases that some of the requested query variables are already present in the input dataset or that the queries dataset contains duplicates. (#2543)

  • derive_vars_atc() and create_single_dose_dataset() by_vars argument updated to use get_admiral_option("subject_keys") instead of USUBJID or STUDYID in bds_exposure.Rmd. (#2501)

  • test scripts, R, and markdown files for create_single_dose_dataset and occds.Rmd updated to include a STUDYID column because of get_admiral_option("subject_keys") update above. (#2501)

  • In get_summary_records(), previously deprecated formal arguments analysis_var and summary_fun now removed from function, documentation, tests etc. (#2521)

Breaking Changes

  • The following function arguments are entering the next phase of the deprecation process: (#2487)

Phase 1 (warning)

Phase 2 (error)

  • Adopted data-raw/data R Package Convention (#2427)
  • compute_bsa() now uses the more common (but equivalent) version of the DuBois-DuBois formula for BSA. The results have not changed. (#2532)
  • Removed .devcontainer file (codespace) (#2524)

admiral 1.1.1

  • derive_extreme_event() was fixed such that check_type = "none" is accepted again. (#2462)

admiral 1.1.0

New Features

  • Added helper functions to derive_vars_merged() (get_flagged_records()) and derive_vars_query() (get_vars_query()) so that those can be called independently as per user's request. derive_vars_merged() function call results are not impacted by the change (#2441).

  • Error Messaging has been made more "user-friendly". (#2372)

  • New country_code_lookup() metadata added to decode countries based on ISO 3166 codes. (#2388)

Updates of Existing Functions

  • Templates for ADPC, ADPPK and ADPP are updated to handle urine records. (#2392)

  • create_single_dose_dataset() has been updated to error if the lookup_table contains duplicates. (#2247)

  • derive_vars_merged() and derive_vars_transposed() have a relationship argument added (the same as found in dplyr::*_join() functions) for users to specify what type of join (one-to-one, one-to-many, etc.) should take place. (#2247)

  • basket_select() function updated to add ... argument to allow other qualifiers to be passed to user-defined function specified in get_terms_fun() argument for function create_query_data(). (#2265)

  • Messaging updated for derive_extreme_event() to improve clarity around duplicates. #2405

  • The id_vars argument was added to derive_vars_transposed() and derive_vars_atc() to allow additional variables, beyond those in by_vars, to uniquely identify records in the dataset_merge argument. (#2325)

  • Update PK Programming vignette and templates for ADPC and ADPPK for the nominal time formula NFRLT to reduce duplicate records in dose expansion with create_single_dose_dataset(). (#2426)

  • Template for ADSL updated so that EOSSTT is assigned as "ONGOING" when no study completion rows exist yet in DS. (#2436)

  • The slice_derivation() function was updated such that it works now when called in a function where objects from the function environment are used. (#2244)

Breaking Changes

  • The following function arguments are entering the next phase of the deprecation process: (#2299)

    • compute_egfr(wt)
    • consolidate_metadata(check_keys)

  • The following function arguments have reached the end of the deprecation process and been removed: (#2299)

    • dthcaus_source(traceability_vars)
    • date_source(traceability_vars)
    • derive_var_ontrtfl(span_period)
    • derive_var_shift(na_val)
    • derive_vars_aage(unit)

Documentation

  • Documentation for derive_extreme_event() has been updated to include a description for the value of derive_extreme_event() when keep_source_vars = NULL. (#2398)

  • The "Visit and Period Variables" vignette was updated and refactored to include example code to create a period reference dataset. (#2321)

  • The documentation of derive_vars_merged() function is updated to describe that the check_type argument is ignored (an error is issued) if order is not specified. (#2326)

  • The "User Guides" section has been reorganized. A new "Programming Concepts and Conventions" vignette was also added to provide more context and information around common {admiral} behaviors and ways of working. (#2395)

  • The "Get Started" section has been revamped, placing greater focus on material that may help users familiarize themselves with {admiral}. There are now new sections showcasing the various types of {admiral} functions and some of the more advanced topics have been moved to the new "Programming Concepts and Conventions" vignette. (#2395)

  • The Examples section of derive_param_computed() now contains a new item showcasing how to create a derived parameter in the case that a variable contributing to the derived parameter has some/all of its values missing. (#2338)

Various

  • Templates and vignettes do not add or populate AVALC for BDS-findings datasets where the information contained in AVALC would be redundant with AVAL. (#2442)

  • The function dplyr::transmute() is superseded in favor of dplyr::mutate(.keep = "none"). Consequently, all the admiral functions that utilized the former have been updated accordingly. (#2274)

  • The templates for ADPP and ADPC are updated for missing variables (#2308) and to make ATPT and ATPTN consistent. (#2328)

  • ADLB template updated to make PARAM consistent for PARAMCD values "BASO" and "LYMPH". (#2327)

Developer Notes
  • In the previous version, renv was the default framework used to manage package dependencies. Now, we use devtools as our main package manager (some changes also occurred for admiralci workflows). There is a possibility to get package dependency versions used for the workflows to ensure local reproducibility. For this, you need to go under the latest action summary in your current PR. You can see a deps artifact. For each version of R used for R CMD CHECKS jobs, there is an associated renv.lock file (under the deps artifact).
  • Splitting out R and test files for date/time functions for cyclomatic complexity refactor (#2340)(#2339)
  • Created three unit tests for get_summary_records(). (#2304)
  • Created unit tests for developer internal function get_imputation_target_date() (#2378)
  • Modified date/time unit tests to use unified example (#2424)

admiral 1.0.2

  • Fix bug in derive_param_tte() where argument dataset populated and PARAMCD in set_values_to argument is an expression. Previously, there was a check early in function to see if PARAMCD defined in set_values_to argument, already existed in the dataset passed into dataset argument. If PARAMCD was not an expression i.e. PARAMCD = "XYZ" then check worked. However, if PARAMCD to be created was an expression, and wasn't resolved yet, this caused an ERROR. The check has been moved to near the end of the function, where PARAMCD is resolved in the dataset holding the new parameters. (#2336)

admiral 1.0.1

  • Fix bug in derive_vars_query() where if AE terms were in mixed case no terms are flagged. (#2311)

admiral 1.0.0

New Features

  • The new function derive_vars_extreme_event(), which works as derive_extreme_event() but adds variables instead of a parameter. (#2138)

  • The new function derive_var_merged_ef_msrc() is provided to add a flag indicating if one of the conditions in one of multiple source datasets is fulfilled. (#1728)

  • New global option created signif_digits and added to set_admiral_options() to handle floating point issue, the value is set to 15, and is used with the base R function signif() when comparing 2 numeric values. This is implemented in admiral functions derive_var_atoxgr_dir() and derive_var_anrind(). (#2134)

    For more information, please see blog: How admiral handles floating points

  • The new function derive_vars_computed() is provided which has the same functionality as derive_param_computed() but instead of adding the computed values as a new parameter, adds it as a new variable. (#2178)

Updates of Existing Functions

  • Fixed a bug in compute_tmf() where the time imputation flag was being incorrectly populated when any of the existing time components (hour, minute and/or second) of the date character vector ('--DTC'), was imputed. (#2146)

  • derive_extreme_records(), derive_var_extreme_flag(),derive_vars_joined() and derive_vars_merged() were enhanced with the arguments true_value and false_value to align with preexisting functions that had similar functionality. (#2125)

  • restrict_derivation() now allows {dplyr} functions like mutate() in the derivation argument. (#2143)

  • derive_summary_records(), derive_var_merged_summary(), and get_summary_records() were enhanced such that more than one summary variable can be derived, e.g., AVAL as the sum and ADT as the maximum of the contributing records. (#1792)

  • derive_summary_records() was enhanced with the following arguments: dataset_add (required), dataset_ref (optional), missing_values (optional). These arguments respectively, generate summary variables from additional datasets, retain/add specific records from a reference dataset, and impute user-defined missing values. Note that dataset_add can be set to the same value as dataset if a different additional dataset is not required. derive_param_exposure() was enhanced with dataset_add as well. (#2142)

  • The missing_values argument was added to derive_var_merged_summary(). It allows to define values for by groups, e.g., subjects which are not in the additional dataset. (#2230)

  • The argument dataset is now optional for derive_summary_records() and derive_param_exposure(). (#2142)

  • The "joined" functions (derive_vars_joined(), derive_var_joined_exist_flag(), filter_joined(), and event_joined()) were unified: (#2126)

    • The dataset_add and filter_add arguments were added to derive_var_joined_exist_flag() and filter_joined().
    • The filter argument was renamed to filter_join in derive_var_joined_exist_flag() and filter_joined().
    • The tmp_obs_nr_var, the join_type, the first_cond_lower, and the first_cond_upper arguments were added to derive_vars_joined().
    • In derive_var_joined_exist_flag(), filter_joined(), and event_joined() the first_cond argument was renamed to first_cond_upper and the first_cond_lower argument was added.
    • In all "joined" functions the filter_add argument is applied to the additional dataset grouped by by_vars and the filter_join argument is applied to the joined dataset grouped by the observations from the input dataset. I.e., summary functions like all() or any() can be used.

  • The tmp_event_nr_var argument was added to derive_extreme_records() to allow more control of the selection of records. It creates a temporary variable for the event number, which can be used in order. (#2140)

  • signif_dig argument added to both derive_var_atoxgr_dir() and derive_var_anrind() functions with default value set to general option signif_digits. The new argument to these functions handles any floating point issues. (#2134)

  • Fixed a bug in derive_vars_period() where the function was throwing an error whenever dataset_ref contained variables that were neither key variables, nor APERIOD, ASPER, APHASEN, nor mentioned in the new_vars argument. (#2231)

  • compute_duration(), derive_vars_duration(), derive_vars_aage() now accepts more terms for the in_unit, out_unit, and age_unit arguments (#2255)

  • Updated the unit test for derive_var_obs_number(). The new test checked the derivation of the default and customized new_var, sorting with the the missing value and expected conditions. (#2260)

  • The check for existence of TERMNUM/TERMCHAR in queries dataset is now less strict depending on values of SRCVAR for derive_vars_query() (#2264)

  • DAIDS grading criteria fixed for Grade = 0 for TERM = "Absolute Lymphocyte Count, Low", criteria was AVAL <= 0.65, now corrected to AVAL >= 0.65 (#2284).

  • A bug in derive_extreme_event() was fixed. The condition field is no longer ignored if mode is specified for event() (#2291).

  • A bug in derive_vars_joined() was fixed. The function no longer fails if renaming is used in by_vars and new_vars is not specified (#2289).

Breaking Changes

  • {admiral} now only supports R >= 4.0.0

  • In derive_extreme_records() the dataset_add argument is now mandatory. (#2139)

  • In derive_summary_records() and get_summary_records() the arguments analysis_var and summary_fun were deprecated in favor of set_values_to. (#1792)

  • In derive_summary_records() and derive_param_exposure() the argument filter was renamed to filter_add (#2142)

  • In derive_var_merged_summary() the arguments new_var, analysis_var, and summary_fun were deprecated in favor of new_vars. (#1792)

  • In derive_vars_merged(), the argument match_flag was renamed to exist_flag (#2125)

  • The default value for the false_value argument in derive_extreme_records() was changed to NA_character_ (#2125)

  • In consolidate_metadata(), the argument check_keys was renamed to check_type to align with other functions (#2184)

  • In filter_joined() and derive_var_joined_exist_flag() (#2126)

    • the first_cond argument was deprecated in favor of first_cond_upper and
    • the filter argument was deprecated in favor of filter_join.

  • In event_joined() the first_cond argument was deprecated in favor of first_cond_upper. (#2126)

  • In derive_extreme_event(), the ignore_event_order argument was deprecated and the selection of the records was changed to allow more control. Before, the records were selected first by event and then by order. Now they are selected by order only, but the event number can be added to it.

    To achieve the old behavior update

order = exprs(my_order_var),
ignore_event_order = FALSE,

to

tmp_event_nr_var = event_nr,
order = exprs(event_nr, my_order_var),

and

order = exprs(my_order_var),
ignore_event_order = TRUE,

to

order = exprs(my_order_var),

  • create_query_data() and derive_vars_query() were updated to rename variables in query data set as follows: (#2186)

    • TERMNAME to TERMCHAR
    • TERMID to TERMNUM

    Users need to adjust their get_terms() function accordingly.

  • The following functions, which were deprecated in previous {admiral} versions, have been removed: (#2098)

Documentation

  • The documentation of the by_vars and constant_by_vars argument was improved and unified across all functions where it is used. (#2137)

  • The functions assert_db_requirements(), assert_terms(), assert_valid_queries(), extend_source_datasets(), filter_date_sources(), validate_basket_select(), validate_query() are no longer exported and have had documentation removed. (#2220)

  • The function extract_duplicate_records() has been re-classified as an internal function, which means that the function still appears in our help pages but not on our website. (#2220)

  • The "Generic Functions" vignette (now "Generic Derivations") was rewritten. Now it provides a more complete overview of the generic derivations, describe the common concepts, and makes it easier to find the appropriate function. (#2230)

  • A way to standardize roxygen labels and descriptions for function arguments was implemented and tested. (#2034)

  • A link to published CDISC Population PK (ADPPK) implementation guide was added. (#2161)

  • Removed Deprecation section in Reference tab. Added new Superseded section in Reference tab. (#2174)

  • Added a link to the previous versions of the website to the navigation bar. (#2205)

  • The meaning of date_imputation = "mid" was clarified in the documentation of the imputation functions, e.g. derive_vars_dtm(). (#2222)

  • Added an example derivation of DTHCGR1 to the ADSL vignette. (#2218)

  • Moved Development Process from {admiraldev} to Contribution Model in the admiral website, updated GitHub strategy. (#2196)

  • Added new drop downs in Get Started navigation bar- Getting Started, Admiral Discovery, Cheatsheet. Community removed from top. (#2217)

  • All "Example Script(s)" sections in the User Guide vignettes were updated to point the user towards using use_ad_template("ADaM") rather than linking to the template in the code repository. (#2239)

  • Handling of NA values was added to the documentation of the order argument for all functions. (#2230, #2257)

Various

  • Website now has button/links to Slack channel and GitHub Issues. (#2127)

  • Added example derivations of DTHCAUS and DTHCGR1 to the ADSL template. (#2218)

  • Cheat Sheet now added to website front page (#2130)

admiral 0.12.3

  • Fixed a bug in derive_var_dthcaus() where if a subject has observations in more than one of the sources, the one from the last source was selected regardless of the date. Now the function works as described in its documentation. (#2154)

admiral 0.12.2

  • A unit test for derive_param_computed() was modified in anticipation of major user-facing changes to R version 4.4 (#2147)

admiral 0.12.1

  • derive_extreme_records() no longer fails if dataset_add is specified and a variable specified for order is not in dataset. (#2113)

  • The type argument in compute_duration() changed the underlying default behavior in derive_vars_duration() without allowing the user to toggle between "duration" and "interval" as originally intended. This was fixed by adding the type argument for derive_vars_duration() and a wrapper function derive_vars_aage() such that it gets passed through compute_duration() appropriately (#2112)

  • Template ad_adpp.R updated to replace left_join() with derive_vars_merged() (#2109).

admiral 0.12.0

New Features

  • atoxgr_criteria_daids.rda added, which holds metadata for Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events. You can find additional documentation here atoxgr_criteria_daids()

Updates of Existing Functions

  • The functions derive_param_bmi() and derive_param_bsa() are updated to have the option of producing more values at visits when only weight is collected (#1228).

  • The functions derive_var_age_years() and compute_age_years() are updated to return an NA age in the case that the age unit is missing. (#2001) The argument unit for derive_vars_aage() is also changed to age_unit for consistency between these age-related functions. (#2025)

  • The derive_var_ontrtfl() function has been updated to allow for the column passed in ref_end_date to contain NA values. Previously, if the end date was NA, the row would never be flagged. Now, an NA value is interpreted as the treatment being ongoing, for example. (#1984)

  • The function derive_var_extreme_flag() has a new function argument, flag_all that additionally flags all records if the first or last record is not unique. (#1979)

  • The function derive_param_computed() was enhanced: (#1968)

    • The analysis_value and analysis_var arguments were deprecated in favor of set_values_to. This enables users to compute more than one variable.
    • The keep_nas argument was added. If it is set to TRUE, observations are created even if values contributing to the computed values are NA.

  • The function derive_vars_dy() is updated to avoid potential error when the input dataset with columns ending with temp. (#2012)

  • Argument keep_source_vars was added to derive_extreme_records() which specifies which variables in the new observations should be kept. (#1697)

  • Templates, vignettes, and other uses of {admiral.test} SDTM data are updated to use {pharmaversesdtm} instead. (#2040)

  • The traceability_vars argument in date_source() and dthcaus_source were deprecated in favor of set_values_to. The date_source() function creates a date_source object as input for derive_var_extreme_dt() and derive_var_extreme_dtm(),users can now define the traceability variables by assigning those variables to the set_values_toargument.Similarly, the dthcaus_source creates a dthcaus_source Object. (#2068)

  • derive_extreme_event() was enhanced (#1960):

    • event_joined() events can be specified for the events argument. This allows to define events based on more than one observation, e.g., events which need to be confirmed by a second assessment.

    • The source_datasets argument was added to the function and the dataset_name field to event(). It can be used to define events based on a different dataset than the input dataset.

    • The keep_source_vars argument was added to the function and the keep_source_vars field to event(). It allows to select which variables should be kept for the selected observations.

    • The mode and order field were added to event(). They allow to select the first or last observation per by group if there are multiple observation fulfilling the event condition.

    • The ignore_event_order argument was added.

    • The description field was added to event(). It can be used to provide a description of the event in plain language.

  • derive_var_atoxgr_dir() was enhanced (#1859):

Breaking Changes

  • The analysis_value and analysis_var arguments in derive_param_computed() were deprecated in favor of set_values_to (#1968).

  • The na_val argument in derive_var_shift() has been deprecated in favor of missing_value using the first phase of the deprecation process. (#2014)

  • The dataset_expected_obs argument in derive_expected_records() and derive_locf_records() has been deprecated in favor of dataset_ref. (#2037)

  • The span_period argument in derive_var_ontrtfl() has been updated to only accept TRUE or FALSE, where is previously accepted "Y" and NULL. (#2033)

Documentation

  • Non-exported utility and print functions were previously listed on the admiral website reference page. They have been removed. (#2049, #2050)

  • The description of the argument reference_date in the function derive_vars_dy() has been clarified to make it agnostic to start/end selection. (#2027)

  • Date and Time Imputation User Guide/Vignette has section on preserving partial dates updated (#2028)

Various

  • The list of package authors/contributors has been reformatted so that those who are actively maintaining the code base are now marked as authors, whereas those who made a significant contribution in the past are now down as contributors.

    • VAR_PREFIX to PREFIX
    • QUERY_NAME to GRPNAME
    • QUERY_ID to GRPID

Documentation

  • Updated example dataset to trigger deterioration flags in the vignette "Creating Questionnaire ADaMs". (#1853, #1854)

  • Updated PK Programming vignette to include new Population PK Template ad_adppk.R. (#1772)

  • Updated "Lab Grading" Vignette to link to grading metadata available in {admiral} and clarify how abnormal baseline values are assigned in NCI-CTCAEv5. (#1863)

  • Updated "Visit and Period Variables" Vignette to add more detail about Study Specific Code that is required. (#1831)

  • Increased documentation for those functions which are regarded as wrapper functions. (#1726)

  • Examples in function documentation no longer rely on library(admiral.test). (#1752)

  • Conferences where {admiral} was presented were updated on the README.md. (#1890)

Various

  • vars() which was used in the admiral function calls that expected a list of quosures has been removed. The admiral option force_admiral_vars was removed as well. (#1694)

  • derive_vars_dtm() and derive_vars_dt() had a bug pertaining to imputations associated with supplying both min_dates and max_dates that has now been resolved. (#1843)

  • External functions are now consistently imported via namespace. package::function() calls have been removed from admiral functions. (#1842)

  • restrict_derivation() had a bug which led to failure if the derivation argument was not in the global environment. (#1765)

admiral 0.10.2

  • Changing package maintainer from Thomas Neitmann to Ben Straub. (#1848)

admiral 0.10.1

  • Fix checks on derive_vars_dtm() and derive_vars_dt() that were too restrictive. (#1810)

admiral 0.10.0

New Features

  • Using {testthat} 3rd edition for unit testing. This is stricter in that messages must be addressed and deprecated functions throw errors. (#1754)

  • New function consolidate_metadata() for consolidating multiple meta datasets into a single one. (#1479)

  • New function compute_scale() for computing the average of a vector and transforming the result from a source to a target range. (#1692)

  • New ADPC template script available ad_adpc.R which creates PK Concentration Analysis Dataset (#849). This script includes formatting suitable for Non-Compartmental Analysis (ADNCA). (#851)

  • New function derive_expected_records() for adding expected records. (#1729)

  • New function derive_extreme_event() for adding the worst or best observation for each by group as new records. (#1755)

Updates of Existing Functions

  • Arguments analysis_var, keep_vars were added to derive_locf_records(),
    analysis_var allows to specify analysis variable, keep_vars keeps variables that need carrying the last observation forward other than analysis_var (e.g., PARAMN, VISITNUM). (#1636)

  • The function create_single_dose_dataset() adds support for expanding relative nominal time (e.g. NFRLT) used in Pharmacokinetic (PK) analyses. The new parameter nominal_time defaults as NULL and does not change the normal operation of the function. If a nominal_time is specified such as NFRLT (Nominal Relative Time from First Dose) then the nominal time is incremented by the interval specified in EXDOSFRQ for example for "QD" records the NFRLT is incremented by 24 hours, e.g. 0, 24, 48... (#1640)

  • create_single_dose_dataset() is also updated for values of EXDOSFRQ with units in days but expected values less than 24 hours, such as "BID", "TID", and "QID". Previously these values of EXDOSFRQ may result in duplicate records where the day values are incremented but the time values are not. (#1643)

  • The function derive_var_confirmation_flag() and filter_confirmation() gained the tmp_obs_nr_var argument. It helps flagging or selecting consecutive observations or the first or last observation in a by group. (#1724)

  • The functions derive_vars_merged(), derive_var_merged_cat(), derive_var_merged_character(), derive_var_merged_exist_flag(), derive_var_merged_summary(), and derive_vars_merged_lookup() were updated to allow renaming in the argument by_vars. (#1680)

  • The units "min" and "sec" are added as valid values of out_unit in compute_duration() and derive_vars_duration(). (#1647)

  • The function derive_vars_query() now includes a consistency check for QUERY_SCOPE and QUERY_SCOPE_NUM values. (#652)

  • Argument new_var in derive_param_extreme_event() is made optional. (#1630)

  • derive_vars_last_dose() no longer fails if USUBJID is not included in the input dataset. (#1787)

Breaking Changes

  • All function arguments which expected a list of quosures created by vars() are now expecting a list of expressions created by exprs(). For example, instead of by_vars = vars(STUDYID, USUBJID) by_vars = exprs(STUDYID, USUBJID) must be used now.

    To enable running old scripts using vars() in the admiral function calls admiral redefines the vars() function such that it returns a list of expressions. This can be disabled by the admiral option force_admiral_vars (see set_admiral_options()). Please note that this is a temporary solution and will be removed in a future admiral release. (#1627)

  • Function derive_param_tte() has been updated such that only observations are added for subjects who have both an event or censoring and an observation in dataset_adsl. (#1576)

  • Function derive_var_disposition_status() has been deprecated, please use derive_var_merged_cat() instead. (#1681)

  • Function derive_var_worst_flag() has been deprecated, in favor of slice_derivation()/derive_var_extreme_flag(). (#1682)

  • Function derive_vars_disposition_reason() has been deprecated, in favor of derive_vars_merged(). (#1683)

  • The following functions have been deprecated from previous {admiral} versions using the next phase of the deprecation process: (#1712)

    • meddra_version, whodd_version, get_smq_fun and get_sdg_fun from the create_query_data() function
    • date_imputation, time_imputation and preserve parameters from date_source() function
    • filter parameter from derive_var_extreme_flag()

  • ADLB metadata data set called atoxgr_criteria_ctcv5 updated to remove unit check for HYPERURICEMIA as grade criteria based on ANRHI only. This metadata holds criteria for lab grading based on Common Terminology Criteria for Adverse Events (CTCAE) v5.0. (#1650)

  • Renamed derive_var_confirmation_flag() and filter_confirmation() to derive_var_joined_exist_flag() and filter_joined() respectively. (#1738)

  • Added an imputation example for create_single_source_dataset() in function documentation. (#1408, #1760)

  • Updates to examples for derive_var_age_years() and derive_vars_duration(). (#1620, #1634)

  • Increased the level of documentation for derive_var_age_years() to describe the data type of the newly created new_var column. (#970)

Various

  • Functions derive_vars_dtm() and derive_vars_dt() had a bug pertaining to imputations associated with NA values that has now been fixed. (#1646)

  • New function convert_na_to_blanks() to convert character NA to blanks. (#1624)

Updates of Existing Functions

  • Function derive_param_first_event() has been replaced by a more generalized derive_param_extreme_event() function with new argument mode allowing for the selection of either the "first" or "last" event record according to the conditions provided. Also the date_var argument has been replaced with the order argument instead. In addition, three new arguments new_var, true_value, and false_value have been added to allow the user to choose what variable is used to indicate whether an event happened, and the values it is given. (#1317, #1242)

  • Argument ignore_time_for_ref_end_date was added to derive_var_ontrtfl(), which controls if time is considered for the condition if start_date is after ref_end_date + ref_end_window days. (#989)

  • derive_var_atoxgr_dir() default value of atoxgr_criteria_ctcv4 removed for parameter meta_criteria. Can now also choose atoxgr_criteria_ctcv5 for parameter meta_criteria, to implement NCI-CTCAEv5 grading criteria.

  • Environment objects were consolidated into a single admiral_environment object under R/admiral__environment.R. (#1572)

  • The default value of the keep_source_vars argument in create_single_dose_dataset() was updated such that it takes the values of the other arguments into account and the start_datetime and end_datetime arguments are optional now. (#1598)

  • Function create_query_data() has been updated such that the dictionary version is stored in the output dataset. (#1337)

Breaking Changes

  • Function derive_param_first_event() has been deprecated. Please use derive_param_extreme_event() with the order argument instead of the date_var argument. (#1317)

  • Functions smq_select() and sdg_select() have been deprecated and replaced with basket_select(). In the create_query_data() function, meddra_version and whodd_version argument has been replaced by version and get_smq_fun and get_sdg_fun argument by get_terms_fun. (#1597)

admiral 0.8.0

New Features

  • get_summary_records() creates summary records e.g. derive analysis value (AVAL) from multiple records, only keeping the derived observations (#525)

  • derive_param_framingham() adds a Parameter for Framingham Heart Study Cardiovascular Disease 10-Year Risk Score (#977)

  • compute_qual_imputation() imputes values when qualifier exists in character result (#976)

  • derive_var_atoxgr_dir() derives lab toxicity/severity grade for low lab values (ATOXGRL) or for high lab values (ATOXGRH). The grading is created from metadata.

  • New metadata data set called atoxgr_criteria_ctcv4 which holds criteria for lab grading based on Common Terminology Criteria for Adverse Events (CTCAE) v4.0

Updates of Existing Functions

  • list_tte_source_objects() gains a package parameter and is now exported (#1212)

  • The imputation functions (derive_vars_dtm(), derive_vars_dt(), convert_dtc_to_dtm(), convert_dtc_to_dt()) have been enhanced to address users feedback (#1300):

    • Partial dates with missing components in the middle like "2003-12-15T-:15:18", "2003-12-15T13:-:19", "2020-07--T00:00" are handled now.

    • The control of the level of imputation has been refined by adding the highest_imputation argument. For example, highest_imputation = "D" requests imputation for day and time but not for year and month.

      (For the date_imputation and the time_imputation argument NULL is no longer a permitted value.)

    • It is now possible to impute completely missing dates by specifying highest_imputation = "Y" and the min_dates or max_dates argument.

I.e., if a derivation like last known alive date is based on dates, DTC variables have to be converted to numeric date or datetime variables in a preprocessing step. For examples see the ADSL vignette. The following arguments were deprecated:

    • date_imputation, time_imputation, and preserve in date_source()

    The following arguments no longer accept DTC variables:

    • date in date_source(), dthcaus_source(), censor_source(), and event_source()
    • dose_date and analysis_date in derive_vars_last_dose(), derive_var_last_dose_amt(), derive_var_last_dose_date(), derive_var_last_dose_grp()

    The following functions were deprecated:

    • derive_vars_merged_dt()
    • derive_vars_merged_dtm()

  • For the date_imputation and the time_imputation argument of the imputation functions (derive_vars_dtm(), derive_vars_dt(), convert_dtc_to_dtm(), convert_dtc_to_dt()) NULL is no longer a permitted value. The level of imputation can be controlled by the highest_imputation argument now.

  • The following functions, which were deprecated in previous {admiral} versions, have been removed:

    • derive_var_disposition_dt()
    • derive_var_lstalvdt()

  • derive_var_shift() - Derives a character shift variable containing concatenated shift in values based on user-defined pairing (#944)

  • derive_var_analysis_ratio() - Derives a ratio variable based on user-supplied variables from a BDS dataset, e.g. ADLB. (#943)

  • derive_param_wbc_abs() - Adds a parameter for lab differentials converted to absolute values. (#941)

ADPP

  • New ADPP template script available ad_adpp.R which creates Pharmacokinetics Parameters Analysis Dataset (#850)

Updates of Existing Functions

  • Datasets internal to the package have been renamed with prefix admiral_, e.g. adsl has been renamed to admiral_adsl. Corresponding SDTM datasets in {admiral.test} have also been renamed, e.g.dm to admiral_dm. These changes will impact examples, vignettes, unit tests and templates (#1108 and #1088)

  • When derive_vars_dtm_to_tm() was called for variables created by derive_vars_dtm() the function failed. This bug was fixed (#1097).

  • impute_dtc() - Fixed imputation bug. A user setting date_imputation = MID and preserve = FALSE would expect the date 2019---07 to be imputed to 2019-06-30, but the function was returning 2019-06-15. Now returns it correctly. This bug fix also addresses the issue in the downstream functions derive_vars_dt() and derive_vars_dtm(). (#1081)

  • format_eoxxstt_default() - Updated to have a more meaningful parameter name i.e. the parameter that was x is now status (#911)

Breaking Changes

  • derive_var_lstalvdt() has been deprecated in favor of derive_var_extreme_dt() (#753).

  • derive_vars_disposition_reason() now is updated such that the default is populating DCSREASP only when DSDECOD is equal to 'OTHER', which is consistent with ADaMIG_v1.3 (#886).

  • derive_vars_suppqual() has been removed from {admiral} as adding supplementary qualifiers is now done in another package called {metatools} in a function called combine_supp() and is available on CRAN (#950)

  • The filter parameter in derive_var_extreme_flag() and derive_var_worst_flag() has been deprecated in favor of restrict_derivation() (#701).

  • The following functions and parameters, which were deprecated in previous {admiral} versions, have been removed (#1056):

    • derive_agegr_ema()
    • derive_agegr_fda()
    • derive_disposition_dt()
    • derive_disposition_status()
    • derive_extreme_flag()

    • derive_last_dose()
    • dataset parameter in lstalvdt_source and dthcaus_source

  • The following functions were deprecated in favor of derive_vars_dy() (#1076):

    • derive_var_ady() - Derive Analysis Study Day
    • derive_var_aendy() - Derive Analysis End Relative Day
    • derive_var_astdy() - Derive Analysis Start Relative Day

  • The following functions were deprecated in favor of derive_vars_merged_dtm() (#1076):

    • derive_var_trtedtm() - Derive Datetime of Last Exposure to Treatment
    • derive_var_trtsdtm() - Derive Datetime of First Exposure to Treatment

  • The derive_var_disposition_dt() function was deprecated in favor of derive_vars_merged_dt() (#1076)

  • The derive_var_atirel() function was deprecated, as it is deemed as too specific for admiral. Derivations like this can be implemented calling mutate() and case_when().

Documentation

  • Additional explanation added to derive_param_* and derive_derived_param functions regarding which variables are populated in the additional rows (#939)

  • Updated derive_var_worst_flag() and derive_var_extreme_flag() vignettes to clarify their purpose (#691)
