Hi,
I'm writing, on GNU/Linux (Debian), some code with rpy, that should
work also (actually mainly) on Windows. Today I've tried to make it
run on Windows, with no success.
The problem is very simple to explain: import rpy does not work;
neither from a DOS shell nor from IDLE or form a script.
I'm using Python 2.3.5 (but I can probably move to 2.4 if needed) and
R 2.3.1.
I've tried the following (sorry for not having the exact errors):
1) trying to import rpy gives an error like:
couldn't obtain version number from output ...
2) the error arises when rpy tries to get RHOME, RVERSION, RVER and
the like. the problem is that
a) if RHOME is not set as an environment variable rpy seems
unable to get it from other sources, but it gets RVERSION
right;
b) if it is set (like C:\Program Files\R\R-2.3.1) then rpy is
unable to get RVERSION because
rpy_tools.get_R_VERSIONS
works with no params but fails if RHOME is given (even if the
value of RHOME is correct, taken from os.environ["RHOME"] or via
rpy_tools.get_R_HOME.
3) so I've tried to edit rpy_options.rpy_options, explicitly setting
RVERSION and RVER [1] (to "2.3.1" and "2031") . By doing so, rpy
"come up" but then fails to load _rpy2031.pyd, simply because
there is no file with that name. There are some _rpy20xx, but
not that one. I've tried also to copy _rpy2021 to _rpy2031 but
that the poor R does not find the entry point (reanonably
enough).
So I'm really lost. But the problem seems to be so "fundamental" that
I hope I'm just making some basic thing wrong.
thanks in advance for any help, Luca
