How do i update R on Cent OS?

Question

I am having issues finding a way to Update R on CentOS.

I ran "yum remove R" and returned a successful message. But when i type R it still loads up the R environment.

Do i need to remove it another way first, before updating? I'm Running R Version 2.15.2

Answer 1

You should be able to just run the following to update your R distribution.

yum update R

Further details are needed if you are having additional problems. Or try removing all the R components separately as noted by @TARehman.

Note - this all assumes you don't need sudo privileges otherwise you would need to make some administrative requests if you aren't the owner of the machine.

On our CentOS machines, R involves a few different things. Running yum list installed | grep R returns:

R.x86_64                                  2.15.2-1.el5                 installed
R-core.x86_64                             2.15.2-1.el5                 installed
R-devel.x86_64                            2.15.2-1.el5                 installed

I'd suggest that you do sudo yum remove on all of them if you're concerned that you're not getting the newest version.
