I am a long time user of R for financial time series analysis (xts, zoo,
etc) and for my next project I am thinking of adding the Python language to
the mix. The reason for adding Python is primarily its non-statistical
capabilities.

So my questions are what have people's experiences been with using interop
between R and Python. I see there are two items, rPy and RSPython. It looks
like rPy makes it possible to call R code from Python, and RSPython goes
both ways. My needs would be to use Python to drive R to get it's extensive
time series and stats, and also to get to Python objects from inside R.

I searched the list archives and it looks like many people use rPy, but what
about RSPython for calling Python from R? It looks like rPy only goes from R
into Python, and RSPython has not been updated since 2005?

Other messages in the archives state that RSPython only works on Unix?

Would I be foolish to build anything mission critical on RSPython? Is there
a better way to get at Python from R?

Thanks as always.
