Install R on Ubuntu 14.04

By Rémi GATTAZ Linux Polytech RICM4

Step 1 : Add the repository

The version of R in the default repository is old. To get the latest version of R, we will have to add a new repository to the package manager.

$ codename=$(lsb_release -c -s)
$ echo "## R repository" | sudo tee -a /etc/apt/sources.list > /dev/null
$ echo "deb https://cran.rstudio.com/bin/linux/ubuntu/ $codename/" | sudo tee -a /etc/apt/sources.list > /dev/null
$ sudo apt-get update

Step 2 : Install r-base

Now that the repository is setup, you can install R.

$ sudo apt-get install r-base

During this step, you might get a warning since the repository's keys are not on the servers.

Step 3 : Try R

As usual, we will try R with a "Hello World". Open a terminal and do the following :

$ R
> print('Hello World!');
[1] "Hello World!"

Step 4 : Install RStudio

There are no version of RStudio in Ubuntu repositories. So to install it, you will need to download it and install it manually.

$ cd ~/Téléchargements/
$ wget https://download1.rstudio.org/rstudio-0.99.484-amd64.deb

A deb file can be installed using dpkg.

$ dpkg -i rstudio-0.99.484-amd64.deb

During this last step, you might get a message saying that you are missing a dependencies. The installation will work anyway, but you should install the packages.

$ sudo apt-get install <missing-package>

Step 5 : Start RStudio
