R installation

Installation of R 3.4.2 for Windows

Download the installer R-3.4.2-win.exe which conains a binary distribution of R-3.4.2 to run on Windows(including 64-bit versions of Windows). Just run this for a Windows-style installer with standard user rights not as administrator. During setup it is better to change the default installation folder to another folder (e.g. to C:\OSGeo4W64\bin\apps\R\R-3.4.2) because write access to this folder is needed using the QGIS Processing Toolbox.
