Greetings, Does the RSPython module work? If so is the RSPython interface supposed to work with Windows? I only found a tar file, so I had to make some modifications to even install it, and I am not sure if that is the reason it is not working. It is not working either from R to Python or vis versa. Meaning I cannot call the one from the other. Can anyone point me to some help other than that on the http://www.omegahat.org/RSPython/ or give me advise? None of my errors relate to the ones described. In R the module loads but then gives me a no R code error and none of the commands work. In python, I can import RS if R is also running, but then even. RS.call or an command gives me a no object error. If R is not running at the same time then the module does not load. Yes, the RSPython is in the path. Thanks, __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!

Dear crog, Yes, it does, but with qualifications. Firstly, the current version is 0.3 which indicates early alpha status, so you should have no expectation that all aspects of it should work or work reliably. We have been able to get it working in both directions (Python -> R and R -> Python), passing both data structures and commands. IMHO, its ability to do that is indistingguishable from magic. However, I have found it segfaults whem producing raster graphics (PNGs) but not Postscript graphics, and a colleague found that it segfaults when passing large data structures (Python tuple to R vector) of 1 million elements or more. A rather tough test. In other respects, under Linux, it has been stable although the shared R library is a bit slow to import (load) into Python (about 1.5 seconds on a 866MHz PIII). Also we had to patch the R makefile to build a shared library in R-1.2.3 but I think this is now fixed in R-1.3.0.

If Duncan Temple Lang (DTL) does not explicitly state that it is intended to work under Windows, then you should assume that it is meant for Unix/Linux only at these early stages. I would be surprised if a Windows version did not surface once it reaches production status, but if DTL's development platform is Unix (and he does work for AT&T after all), then I would expect alpha and beta versions to target Unix/Linux only.

Have you tried emailing Duncan Temple Lang?

I suspect that all of these relate to your use of RSPython under Windows, because we have not encountered these problems under Linux.
