Install R language in CentOs Linux

2014/03/10 Leave a comment

Let’s see how to install R language in CentOs Linux. It is pretty simple:

Trying just that didn’t work…:

yum install R
No package R available.

And this one neither did:

yum install R-core R-devel
No pack…

# Install epel for El6 or CentOS 6
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
yum install R

Ok. Now R is already intelled. Let’s check it out:
