[GRASS-web] r.futures not working

[Anna Petrášová]

Hi,

r.futures.potential calls Rscript, so the error means it can't find the
Rscript binary. If R is installed, I would recommend reinstalling GRASS,
during installation it tries to automatically look for it, so there is a
chance it will work then. I would recommend subscribing to grass-user
mailing list and ask more questions there.
