Set up the repository
---------------------
I used this [repository for the
installation](http://rm.mirror.garr.it/mirrors/CRAN/bin/linux/redhat/el5/i386/).
In `In /etc/yum.repos.d/r-project.repo`:
[r-project]
name=R-Statistics
baseurl=http://rm.mirror.garr.it/mirrors/CRAN/bin/linux/redhat/el5/$basearch
enabled=0
includepkgs=R-core R-devel libRmath libRmath-devel
gpgcheck=0
Resolve the Perl dependency
---------------------------
R needs Perl(File::Copy::Recursive) to install properly. [Get it at the
DAG repo](http://dag.wieers.com/rpm/packages/perl-File-Copy-Recursive/).
Then:
rpm -ivH path.to.perl.rpm
Install R and related libraries
-------------------------------
yum install R-core R-devel libRmath libRmath-devel --enablerepo=r-project
The binary should be in `/usr/bin/R`. Fin!
