Is “guix import cran” not enough?  What is the source of these R packages?

Well, could you be more specific about “using guix to write R packages”?

This seems the job of Guix.

Ricardo wrote a R helper:

Basically, it does more or less what “guix install” does but directly in
the R repl.  Maybe it is what you want.
