[GRASS-stats] Error when starting grass from R (grass installed thru osgeo4w)

[Veronica Andreo]

Hi Helli, Roger

No, I just opened R console (installed outside OSGeo4W) and from there, I
tried to init grass.
Should I open R from OSGeo4W command console and then init grass there? Is
that the workflow?

best,
Vero
