Thanks Hamish for these answers and suggestions. In the meantime we did
end up installing version 7, so I haven't had a chance to test it on 6.4
I was only running as root for installing the extension - I did create a
new mapset just to start grass since the root account didn't have access to
any of the other mapsets. I hope this is OK.
Regarding version 7: is the issue stability, that sometimes it won't work
at all? I am a graduate student, so down time is not critical. But if
experimental means the calculations could be incorrect, I guess that would
be more important. One of the other students is pushing for version 7
since they like the new features.
Should spgrass work with version 7? I saw comments in the mail archive
from over a year ago that GRASS <-> R was much better in version 6 compared
to version 7, is the situation improved now? (It didn't work when I first
tried it, but I have not taken time to check the details yet...)
