[GRASS-stats] Re: [R-sig-Geo] Fail to load a vector layer using spgrass6

The output of ogrDrivers() shows that I do not have the GRASS driver
(tagged as FALSE).

No, I do not have to use it, it is plein curiosity/testing of new
features. However I reproduced the problem on the 6.4 version.

I installed both GRASS 6.4 and GDAL/OGR from binaries, yes.

OK. I am sending that message to that list, and keep R-sig-geo for
consistency. Sorry for cross-posting.

Thanks again,
