I am trying to build and install rpy2 Python Module. But got an error (see below).
I have R installed in C:\\Program Files\\R\\R-2.15.0\\
and R.h
This is because your R include library is not in your CPPFLAGS enviroment variable. You should find the file R.h in your "C:\Program Files\R\R-2.15.0\include". In linux, you can add this to your .bashrc
export "$CPPFLAGS=-I/path-to-R/include $CPPFLAGS"
But i'm not familar to python and R in windows. That's all I can help.
