Hello,
Well, the fix in the source seemed almost too trivial. It seems that the line
of code wherein the exception was thrown uses the R environment "get"
function to attempt to fetch "R.version.string". However, the authors have
attempted to fetch "R_version_string", for which R complains that there is no
such "variable". I changed the source (rpy.py line 307) to read
Rver = self.__getitem__('R.version.string')
as I believe was the original intention. I'm guessing that the procedure in
question (R.__repr__(self)) is never used and so no one has previously
noticed or complained.
Perhaps the re-coding of "." to "_" is some sort of artefact of previous the
previous way rpy called the R "get" function?
