How to upgrade R version on Ubuntu?

There are lots of directives on the web how to upgrade R version or installing the latest version of R. Here I am going to tell the clearest and success way that I have done.

Open your terminal (Ctrl+Alt+T)

1. Uninstall current R version on your system

sudo apt-get remove r-base-core

2. Add cran.rstudio deb to sources.list

sudo nano /etc/apt/sources.list    

Paste the below code in to your sources.list

deb precise/

My version is “precise”.  That’s why the line ends with “precise”. You can learn your Ubuntu version:

lsb_release -a

Codename is your version….

3. Add key to sign CRAN packages

sudo apt-key adv --keyserver --recv-keys E084DAB9

4. Add PPA (for CRAN) to your system

sudo add-apt-repository ppa:marutter/rdev
sudo apt-get update
sudo apt-get upgrade
5. Install R again
sudo apt-get install r-base
If you want to check the version of your R. Open terminal, enter R and type:
That’s all…..
