rPython is not available for Windows. You can see "OS_type: unix" in
its DESCRIPTION. If you want to support Windows systems, take a look
at the reticulate package, which is another R interface to Python.

Create an inst/ directory and put it there, as suggested in "1.1.7
Non-R scripts in packages" in the "Writing R Extensions" manual.
