Hi,
Below is what I did in Ubuntu to no avail.
locate libR.so
/usr/lib/R/lib/libR.so
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/R/lib/libR.so
python
Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import rpy2.robjects as robjects
Traceback (most recent call last):
