sdsfun 0.5.0

  • Add hclustgeo_disc for hierarchical clustering with spatial soft constraints (#13).

  • Add spade_psd for the fast estimation of the SPADE model psd-value.

  • Add sf_gk_proj_cgcs2000() function.

sdsfun 0.4.3

  • Add geodetector_q for the fast estimation of the geodetector q-value.

sdsfun 0.4.2

  • Add check_tbl_na and tbl_all2int functions to better support the gdverse and sesp packages.

sdsfun 0.4.1

  • Fix the bug that causes R to crash when the input x is a factor or character in the discretize_vector function (#12).

  • Implement the formula_varname function to return the corresponding variable names from both formula and data.

sdsfun 0.4.0

  • Improve the handling of n-level categorical variables by generating n-1 dummy variables (#2).

  • Add the spdep_lmtest function for spatial linear model selection (#3).

  • Migrate the moran_test function from the geocomplexity package to sdsfun (#4).

  • Implement the geographical detector's factor detector in ssh_test using Rcpp to enhance performance (#5).

  • Introduce the discretize_vector function to support variable discretization (#6).

  • Apply the loess_optnum function to select the optimal number of discretization intervals (#10).

  • Implement spatial variance calculation in the spvar function, with support for both R and C++ implementations (#11).

  • Rename dummy_vector to dummy_vec for consistency in naming conventions.

  • Add the sf_coordinates function to extract coordinates from sf objects.

sdsfun 0.3.0
