[GRASS-stats] R 3.3.1 and GRASSGIS 7.0.4

[Anna Petrášová]

Hi,

In order for GRASS to be able to find R executables, R must be on the
PATH variable. Follow for example this solution:

https://pvanb.wordpress.com/2014/12/17/access-r-from-grass-gis-on-windows/

to make R accessible from GRASS permanently. A simple but temporary
solution is to open GRASS GIS and paste the path to R in the black
terminal:

set PATH=%PATH%;C:\Program Files\R\R-3.3.1\bin

but this has to be repeated after restarting GRASS session.
