[osgeo4w-dev] error rgdal library if used from within Grass plugin (Windows)

[Agustin Lobo]

Hi!

The following error only occurs if the R (2.7.2) session is started
from a GRASS shell opened through the QGIS GRASS plugin in windows.
The error does not occur If R is started form its own icon
or by double click in the .RData  object,  but then the spgrass6
package would not find the GRASS environment.

It also works in linux.
The involved  commands  are:

1. Start  QGIS
2. Star GRASS plugin and open mapset
3.  Open Grass Shell
4.  Run R and execute require(spgrass6)

Any help appreciated.
