R SIG Debian - Jul 2011 - Getting confused with two versions of R‏‏

Hi there, I used to run R 2.10 on Ubunutu 10.04, and tried to install R 2.11
from the source at the same time.It seems that doing the second installation, I
have messed up with some files or system paths, resulting in not being able to
use either version of R on my system.
I get the following message in terminal, whenever I try to run R now:

/usr/local/bin/R: line 227: /usr/local/lib/R/etc/ldpaths: No such file or
directory/usr/local/bin/R: line 250: /usr/local/lib/R/bin/exec/R: No such file
or directory/usr/local/bin/R: line 250: exec: /usr/local/lib/R/bin/exec/R:
cannot execute: No such file or directory
I've tried to re-install R using apt-get doing:

sudo apt-get updatesudo apt-get remove r-base sudo apt-get autoremove sudo
apt-get install r-base
Although the installation seems to be successful, I get the same error above
trying to run R.Any suggestions how I can clean up all the leftovers from the
previous two installations, and get back to the r-base available in repository?
Thanks,Alireza

Alireza,

If you installed from source, go back to the source directory and run 
'sudo make uninstall'.  Then I would use a GUI interface Synaptic to 
make sure that all R related packages are removed.  Check to make sure 
typing 'R' returns nothing.

Then I would use these instructions to install the latest version of R:
