[GRASS-user] Re: Error running GRASS from R

[Roger Bivand]

There is a specific list for R/GRASS questions:
http://lists.osgeo.org/mailman/listinfo/grass-stats.

I don't know how you you started the R session. I hope you started R within
a running GRASS session, as you seem to be using an existing location. You
mention using initGRASS() which you should never do with an existing
location, unless you really know what you are doing. You do not say whether
you have also used the execGRASS() wrapper from R to run the other commands,
or whether these were run from the command line. More information is needed
- such as does the same script work locally, or when run without the remote
desktop access on the faster computer.
