You might as well install R-2.9.0 while you're at it.

You can download the R-2.9.0.tar.gz to a directory you have access to.
I'll call it ~/Rhome/

uncompress the file with 
tar xvzf R-2.9.0.tar.gz
and then move to the R-2.9.0 subdirectory that will be created.

In that directory, you'll find a file called INSTALL which will give
you very simple clear directions.  Don't try to make a site-wide
installation which isn't appropriate in your case.

The executable will be at 
~/Rhome/R-2.9.0/bin/R

Assuming you have a ~/bin directory, I find the simplest thing is to
make a link in that directory to the executable.

Now the part that might be slightly tricky.  If you can't get someone
with root access to remove the R-2.4.0 installation, it's simple
enough to prevent it clashing with your newer version.  Make the name
of the link in ~/bin/ something slightly different from R, such as RR
or whatever you fancy.  You then start R with that name.
