R packages are not recognized.

I installed R packages using `guix install`, `guix shell` or by adding them to my home configuration, but in none of those ways can I get my R system (which is also installed through guix using system configuration) can recognize those packages.

What is going wrong?

Try installing R and the R packages in the same profile. I'd suggest
installing R as a user instead of system-wide, but that's up to you.

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.
