1. QGIS processing framework is a geoprocessing environment that can be used to call native and third party algorithms from QGIS;

2. The con gurations that are needed to call R are done in the menu Processing in QGIS;

3. In that menu, choose Options; then Providers and then R scripts to insert the 3 necessary paths;

4. For additional information, look for the documentation on Configuring external applications in the corresponding section of the documentation on QGIS processing framework; In particular, a message error might appear if a shell interpreter for GRASS (usually msys.exe, which can be found in most GRASS for Windows

distributions) is not de ned or its path is not set.

The three paths that need to be set should be something like:

1. R scripts folder:

• Windows: C:\Users\...\.qgis2\processing\rscripts;

• Debian/GNU Linux: /home/.../.qgis2/processing/rscripts;

• Mac OSX: /Users/.../.qgis2/processing/rscripts;

2. R folder

• Windows: C:\Program Files\R\R-3.3.0 (see earlier comments);

3. R user library folder

• Windows: C:\Users\...\Documents\R\win-library\3.3

(see earlier comments); and, of course, check activate and choose the bit version of your system if it applies.
