Py exists in two versions: rpy and rpy2. The rpy used to be done and then
abandoned. There is no updated version of rpy for later versions of python.
The rpy2 is not complete. My experience with it is as follows. I had to edit
__init__.py files to force rpy2 to find and load r.dll because the automated
msi-installer did not install it correctly. The command plot(x,y), executed
from rpy2, opens a non-responsive window. Documentation examples are based on
rpy2.robject.packages.importr while the rpy2 (version 2.0.8) has no "packages"
and no "importr". I tried to experiment and discovered that __doc__ strings
are all empty.
The above was sufficient for me to abandon the idea of using RPy.
