[Qgis-user] R scripts not running in Windows

[Ned Horning]

Thanks for the quick reply Victor.

I did not have R configured correctly. I used C:\Program 
Files\R\R-3.0.2\bin for the path to the R folder and after I deleted 
"\bin" the script worked fine.

For the plot problem it appears as if rgdal can't be found although when 
I run R without going through QGIS it gets loaded just fine. I have my 
packages installed in a personal library 
"C:\Users\Ned\Documents\R\win-library\3.0" and maybe that's causing a 
problem? Here is the error from the Rout file.

--
 > tryCatch(find.package("rgdal"), error=function(e) 
install.packages("rgdal", dependencies=TRUE))
Warning in install.packages("rgdal", dependencies = TRUE) :
   'lib = "C:/Program Files/R/R-3.0.2/library"' is not writable
Error in install.packages("rgdal", dependencies = TRUE) :
   unable to install packages
Calls: tryCatch ... tryCatchList -> tryCatchOne -> <Anonymous> ->
