Hello all,
I believe the rpy doc indicates that there is a way to kill the
connection to R within the script if you are on unix flavored OSs. I am
looking for a way to do this on windows. I am working with an
application that runs each python script "In Process", essentially using
PyExecString with a set of predefined local and global dictionaries.
The error that returns is:
RuntimeError: Only one R object may be instantiated per session
>From some other threads on the net I found that this can be duplicated
by:
>>> import rpy
>>> rpy.R()
>> File "C:\Python25\Lib\site-packages\rpy.py", line 346, in
>> r = R()
I don't know what the best solution is for this. Should I be looking to
clean this up by hacking something similar to the "stop_r_eventloop"? Or
should the above function be a No Op if R() has already been
initialized.
Our program (ArcGIS) had a similar issue with numpy when we began using
it. In that case, it happened to be a static variable that was not
cleaned up when we flush the globals and locals after the PyExecString.
Travis O actually set it as a bug and fixed it on their end.
The behavior in short, the first time I run a script that is using rpy,
it works beautifully.... The second time it runs, I get the error
listed. As the locals and globals have been flushed after the first
use, there is no reference to rpy in them or the sys.modules on intial
startup.
I appreciate any help with this matter. Regards,
MJ
