[Matteo Ghetta]

HI Daniel,
you can also find a small small tutorial here:

https://github.com/qgis/QGIS-Documentation/blob/master/source/docs/training_manual/processing/r_intro.rst

You are more then welcome if you want to add some of your scripts or if you
want to write some tutorial/exercise.

Cheers

Matteo
