The code below will install R to the default location for a source install, presuming that you have root access and did not get any errors or warnings as a result of that process.

That begs the question then, how was the prior version of R installed? It sounds like there is a conflict in that the prior version is in a location that precedes the new version in your $PATH.

Commonly, I believe, the executable for R on Linux is installed in /usr/local/bin, but may be elsewhere (eg. /usr/bin), depending upon how it was installed.  You can locate which R is being executed on your system by using:

  which R

in a console.

That will give you some hints as to location. Within the version of R that is running, you can use:

  R.home()

to find out where the old primary R tree has been installed, including packages.  I would use that information to remove the old installation.

If you are on RHEL or a compatible server distribution like CentOS (you did not answer that) and have root access, I would recommend using the EPEL:

  http://fedoraproject.org/wiki/EPEL

to configure your system to use the pre-built binary RPMs for R via yum. You can then use:

  yum install R

as root to install R and also handle future updates via yum. You should remove all vestiges of both the old R install and the new source R install before doing that however.

Regards,

Marc
