qgisrsextante
I am new to QGIS and most of the tutorials I have found are for 1.x and the overhaul has me confused.
I would like to create R scripts and run them in QGIS. I have read here that it's possible using the SEXTANTE plugin.
It seems that SEXTANTE is part of the core install now and that it's been renamed to processing. I've found out how to make python scripts but not R.
Is it possible to create and run custom R scripts in QGIS 2.0? If so, where do I go in the new processing function?
The principle is simple if you have R installed and is usable in command line.
You can create and/or execute a R Script from QGIS using Processing in QGIS version 2.0 or Sextante in version 1.8):
see:
Sextante is now known as Processing and is a core plugin (no need to install). OTB, if using Kyngchaos.com QGIS installer, is included inside the QGIS.app bundle.
Processing should be able to access the OTB applications within the QGIS.app bundle, i.e. with the Kyngchaos.com installer Processing should just work out-of-the-box.
Also bundled within the Kyngchaos.com 2.2 QGIS.app are Grass, Saga and TauDEM commandline tools, for use by Processing.
There are some Processing commands not functioning on Mac, like the Lidar tools, which require Windows.

Sure you can create and run R scripts in QGIS 2.0.
The basic sintaxis is the same as python, so start reading this: http://www.qgis.org/es/docs/user_manual/processing/console.html#creating-scripts-and-running-them-from-the-toolbox
Then you can check, some example scripts installed by default, in your processing panel.
If you need more help you can check some of my scripts:
