Thanks Laurent.
I have installed a VMWare Ubuntu machine and am quite impressed.
Python runs much faster as a Linux VM under Win7 than it did on a dual
boot XP (quad core I7).
However I have been having no end of problems trying to get rpy2 to run.
When I run the tests
python -m 'rpy2tests'
I get the following error
File "/usr/local/lib/python2.6/dist-packages/rpy2/rinterface/__init__.py",
line 75, in <module>
from rpy2.rinterface.rinterface import *
ImportError: libR.so: cannot open shared object file: No such file or directory
I took great pains to compile the R11.1 with the following
./configure --enable-R-shlib
make
make install
which passed OK.
What else could be wrong?
Andrew.
