Some grass modules don't support --interface-description, but I think
not many.
r.mapcalc being the primary concern. Most of the remaining rest are
interactive things which wouldn't be useful from R. I don't think it's
a huge effort to do something special for r.mapcalc, chances are you
might want to do something special with it anyway.
You can use the r.mapcalculator script as a frontend if you need one
with a working --interface-description.
Right, had found that, thanks!
I'd argue that r.mapcalculator will be good enough. If users need all the
strength of r.mapcalc, they can say system("bash") and do it from the
shell, returning to R by closing the shell. The history file for the
under-shell will not, however, be recorded (at least not in the same
place).
