I am running into similar but slightly different problems. I am able to
change path, and have edited the r_interface\__init__.py file to output
what Rlib and os.path are. It guesses the correct location of R.dll, but
still throws an error. I have been doing some reading, and it appears as
though the os.path.exists will fail if you do not have administartor
priviliges when opening. I changed write privileges on all the files (as
well as moving the R installation out of C:\Program Files and into C:\). I
now have os.path.exists(Rlib) output True, but it fails at the
win32.LoadLibrary(Rlib).
My screen dump is below.
Does anybody have any suggestions?
I'm on 64 bit windows 7, but platform.architecture says "32 bit." Could
this be the problem (as the 32 vs 64 bit always seems to be...).
Thanks for any help - I've been slaving away on this for a long time now...
Rpy2 v 2.3.6
Python 2.7.3
R 2.15.3
Thanks!,
Dave
