you don't need to package R yourself, R is already packaged and available
in Guix, i believe.

If you want to package a R based package for Guix you can use the so called
Cran importer

Try this line at the prompt

guix import cran your-R-package

This line invokes a so called importer and the importer should return you
the recipe of your R package written in scheme

You could append such definition to an existing Guix file (probably with
some minor tweaks) and that should allow you to build the package and all
the dependencies will be taken care of automatically

I did this myself some time ago

In order to append the definition of your package to an existing Guix file
you will probably need some more guidance, but for now you could just run
the importer and let us now what you obtained

Probably you'll need to build the package, then modify the recipe a bit,
build it again... for a few times; that's ok

You can read about the importers here

when running Guix on top of a foreign distribution, this problem is very
common.
I lived with this for several months myself

Reaching a solution to this can be tedious and often the solutions are
short lived

Because this has to do with how the basic C libraries provided by Guix and
those provided by the foreign distro relate with each other (usually not so
well)

But this is not critical, you can successfully package some R based
packages for Guix anyway

Hope this helps !
