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

Subject: [Rpy] ImportError: libR.so: cannot open shared object

can t get rpy to work because of this
ImportError: libR.so: cannot open shared object file: No such

* 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'
and run 'ldconfig' as root;
* or set the environment variable LD_LIBRARY_PATH with
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH\
* :R_HOME/bin
*
in your .bashrc (or equivalent).
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.
