Yes I get that it is possible now... but I feel strongly that the
typical R user will be overwhealmed by the guix "wheels and levers".

So I resort to fantasizing a mythical additional guix-specific
component, an 'R "package manager component"'. The idea is to exploit
guix capabilities to make this much more tractable for an average R user
and much more convenient for the sysadmin in charge of providing support
to R users.

Such an 'R "package manager component"' would make the argument for guix
isntallation very compelling for medical research labs.
