I have to take a look at my .bash_history, but I guess somewhere I ran
guix pull because I recall seing something about the $PATH stuff. I
did not run guix output. It doesn'matter, I save my machine state and
run all that now.

Thanks, I took a look at most of the R packages in cran site, and
chose it because of two reasons: it has to do with bioinformatics due
to its description, and as it does not mention imports so I found it
easy for a first R package contribution. If it works fine, then I can
go on packaging more complicated R packages.
