[Qgis-user] Empty Results in R

[Werner Macho]

Hi!

I recently had the same issue..
I don't know if processing is supposed to install missing module 
automatically but the solution for me was to install the missing 
packages "rgrdal" and "raster" on my Computer manually..

R
install.packages();

hope this helps

regards
Werner
