Hi, R doesn’t work on my laptop running capitan [1] My Rutils.py is in the machine /Applications/QGIS.app/Contents/Resources/python/plugins/processing/algs/r/Rutils.py
R_Home is in .bash_proflle export PYTHONPATH="/Applications/QGIS.app/Contents/Resources/python" #R para Qgis export R_HOME=/Library/Frameworks/R.framework/Versions/Current/Resources/ /Library/Frameworks/R.framework/Versions/Current/Resources/ #exists R works typing R in a terminal To get rid of the message claiming that (This happens when trying to activate R ?) /Applications/QGIS.app/Contents/msys is not there I cheated creating it Now I’m able to activate R and download the scripts but an error pop up 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 No problems in other machines running earlier versions of MacOS Best A.
