R -statistical computing

R is a programming language and software environment for statistical computing widely used among statisticians and data miners for developing statistical software and data analysis.

INSTALLATION OF R ON UBUNTU

To obtain the latest package of R,  in your /etc/apt/sources.list file add an entry like:

deb https://<my.favorite.cran.mirror>/bin/linux/ubuntu wily/

At  the place of wily you have to write your own ubuntu version:

• Wily for ubuntu release 15.10
• Vivid for 15.04
• Trusty for 14.04(LTS) and
• Precise for 12.04(LTS)

Replace <my.favorite.cran.mirror> by the actual URL of your favorite CRAN(Comprehensive R Archive Network) mirror. You can choose your favorite mirror accordingly from https://cran.r-project.org/mirrors.html.

For an example I chose USA,CA.

Now to install the complete R system, first update your system by running the following command in terminal:

sudo apt-get update

After updating your system run the following command in order to compile the complete R system from source:

sudo apt-get install r-base-dev

and you are good to go. By just writing ‘R'(without quotes) in terminal you can have the command line interface of R in front of you.
