I have been unable to run R from within QGIS on my computer. I have R version 3.03 installed and QGIS 2.4 on Windows 7. R is located at C:\Program Files\R\R-3.0.3\bin\and this is the path e specified in Processing Options -> Providers -> R Scripts -> R Folder in QGIS.
The error message I receive is
Missing dependency.This algorithm cannot be run :-( This algorithm requires R to be run.Unfortunately, it seems that R is not installed in your system, or it is not correctly configured to be used from QGIS Click here to know more about how to install and configure R to be used with QGIS
I have tried changing the R folder to other R executables, but nothing works.
