don't add the library, just the path to it:
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/R/lib/

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

I think the third option is likely to be the simplest
for you.
First off, find where libR.so actually is. Its probably
somewhere like
/usr/lib/R/lib/ but at the comand line you can type R
RHOME to see the
base of this path.
At home under ubuntu, mine is in /usr/lib/R/lib/ and at
work it is in
/opt/sw/R/2.11.1/lib64/R/lib. Once you have found the
library, try
adding it to LD_LIBRARY_PATH. Say you found libR.so in
/usr/lib/R/lib,
then
you@yourmachine:$ export
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/R/lib
and try running rpy2 now:
you@yourmachine:$ python
>>> import rpy2
In order for you not to have to do this everytime you
want to call rpy2,
you can follow the suggestion in the error message and
add this to
.bashrc (or equivalent); so assuming you use bash, just
edit ~/.bashrc
and add the line:
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/R/lib
to it. Then, either log out and log back in again, or
you@yourmachin:$ source ~/.bashrc

can t get rpy to work because of this

* make a link to R_HOME/bin/libR.so in
/usr/local/lib, or
in some other location that your system knows as a
standard place for
libraries; then run 'ldconfig' as root;
* or edit /etc/ld.so.conf to add the line
'R_HOME/bin'

LD_LIBRARY_PATH with

Can someone provide more color and detail for me
on how to fix
this? This is for this users that are not systems
admis...ldconfig
what?
This happens on a max os and ubuntu.
