You're welcome. It's nice to hear from your progress. Verbosity-level
is fine :-)

Sorry I have no clue of R at all. Could someone else please answer that
question, is r-aspi a good candidate?

Concerning r-abe: I don't know how the list at guix-hpc is created
, how often it is updated or if there are extra packages in there. In
your case, I suppose you lack behind:

There is a commit for r-abe from 2019-09-13, so it is only a month old.
I think you are lacking behind. Have you done a `guix pull`? That's the
command used to update the package definitions.

In case you already did a guix pull recently, and you still don't see
it, there could be a problem with your $PATH, that the wrong guix is
coming first. Do a `which guix`.
Guix should be the one in ~/.config/guix/current/bin/guix

If I see that right, for R we only add the "Imports" packages, as they
are absolutely needed for compiling/running. All "Suggests" can be
installed/used just at runtime. Please correct me anyone if I'm wrong,
I'm not into R.

I haven't done a full review, but that looks good. Next you need to get
the guix sources and prepare a patch.

That's described here:
