R consults the value of the environment variable R_LIBS_SITE to determine the list of directories to search for packages. When R is installed with Guix into a profile, Guix generates an entry in $GUIX_PROFILE/etc/profile that points R to the sub-directory of this profile containing R packages. When you install R packages into a separate profile (and without "r-minimal" or "r") then the generated etc/profile file will not have an entry for R_LIBS_SITE. You can either set this value manually before launching R, use `.libPath` inside an R session to augment the search path, or install R (i.e. "r-minimal" or "r") alongside the packages you intend to use. You can also use "guix shell" with a manifest containing both R and the packages you need; Guix will set R_LIBS_SITE automatically in this case, so that R inside of the Guix environment has access to all requested R packages. -- Ricardo
