I tried to install rpy2 (pip install rpy2). I want to use the SDAPP4 extension with QGIS (QGIS shows up the message missing rpy2...). The system tells me always the same error:
Tried to guess R's HOME but no R command in the PATH. What can I do to solve the problem?
Windows XP Python 2.7 R 2.11.0 (directory: C:\Programme\R\R-2.11.0) QGIS 1.8
Sorry, I'm a beginner.
