Install the latest R on Ubuntu 12.04

Following the default instructions on http://cran.stat.nus.edu.sg/ to install the R with steps below will install an out-dated version (for may case is 2.14):

1) add deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu precise/ to /etc/apt/sources.list
2) run:

sudo apt-get update

sudo apt-get install r-base

To install the latest 3.0 version of R, we need to do the following after modifying the sources.list file :

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9

sudo add-apt-repository ppa:marutter/rdev

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install r-base
