It seems to me that there is some misunderstanding. R, the language itself is
packaged:
(see the variable r-with-test near the top of
gnu/packages/statistics.scm, if you are interested, but I would leave
that for later).
You should try packaging some R package, for example from CRAN.
See https://cran.r-project.org/web/packages/available_packages_by_name.html for
a package list. Please select something that is not already packaged. R packages
in guix are named like r-*. Once you have a candidate, you can use the
cran importer
to generate the package definition.

See it here: 
https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-import.html

Most probably what you are looking for is provided by package xz, but
as I said, you don't need this.

I will have a look at this, and get back to you, but this is not
critical ,you can go on with packaging.
