[GRASS-stats] R packages and GRASS

[Agustin Lobo]

which error? we don't see it. Note you must start R from within
the grass console. Actually it's better if, from the grass console,
you launch xterm & and can start R from the new terminal.

I already downloaded GRASS 6.3, spgrass6 and dependencies and at my first attempt something is happening but I can't quite see a way to import data into R or run commands from R. I ran into the code below yesterday but I can't figure out how to run it from R.
