This (and r-glue too) is an R package designed to be installed and used
from within R. I noticed that the Pandas python package, for example,
doesn't refer to itself as python-pandas in its Guix documentation.
There are numerous other instances in Guix where such library software
for high-level languages refer to themselves and other related packages
as within their own ecosystems instead of the Guix ecosystem. However,
in this particular case I included in parenthesis "(provided by r-glue
in Guix)".

Thanks, I had a look.

I made a few small tweaks which I feel significantly reduces the
"marketing" aspect. See the included patch.
