Re: R graphics windows freezing

Hi Liming,

What versions of rpy and R were you using when you replicated it?
I'm wondering if this is a problem in newer versions of rpy/R and
that maybe using rpy 0.4.6 (which is referenced in the Opus
documentation) with a correspondingly old version of R, would be a
workaround.

If this is the case, could you post the versions of rpy and R that
you use with Opus? (version 0.4.6 of rpy at least does not seem to be
available for download)

Another workaround we've found is to direct the R output to a file
instead of to the screen. Let me know if you would like some example
code.

Thanks,

Brian
