QGIS – Resources for Integrating R for Analysis

Question

I'm finding that much of the QGIS documentation is oriented toward use of the GUI.

I want to be able to run R scripts in QGIS, but am having trouble finding a resource that will ground me in the relationship between QGIS and R data structures and how to pass structures between the two. A related question (Is it possible to create and run custom R scripts in QGIS 2.0?) directed me to this page: http://www.qgis.org/en/docs/user_manual/processing/3rdParty.html, but the I'm finding the documentation there is coming at things from more of a QGIS-expert direction than what I'm looking for.

Any suggestions?

Answer 1

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:

• Setting “R Folder” Path in QGIS Sextante
• Port your R scripts to QGIS using SEXTANTE
• QGIS with R: Working with the SEXTANTE plugin
• and others
