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…..


Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. Advanced users employ Blender’s API for Python scripting to customize the application and write specialized tools; often these are included in Blender’s future releases. Blender is well suited to individuals and small studios who benefit from its unified pipeline and responsive development process. Examples from many Blender-based projects are available in the showcase.

Blender is cross-platform and runs equally well on Linux, Windows and Macintosh computers. Its interface uses OpenGL to provide a consistent experience. To confirm specific compatibility, the list of supported platformsindicates those regularly tested by the development team.

As a community-driven project under the GNU General Public License (GPL), the public is empowered to make small and large changes to the code base, which leads to new features, responsive bug fixes, and better usability. Blender has no price tag, but you can invest, participate, and help to advance a powerful collaborative tool: Blender is your own 3D software.
