Problem installing package 'metap' and 'multtest'

[malemanyc]

Hello all,
I have tried to run the function FindConserverdMarkers() from the lastest docker image and found the following error:

Error: Please install the metap package to use FindConservedMarkers.
This can be accomplished with the following commands: 
----------------------------------------
install.packages('BiocManager')
BiocManager::install('multtest')
install.packages('metap')
----------------------------------------

Once I try to install the multtest and metap packages manually as the message says, I get the following error:

Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)

What can I do now?
Thanks a lot for your help!
