How to install R and R Studio on Ubuntu 16.04

The desktop installation of R is very simple if you are ok with Ubuntu's apt version.

Firstly:
You will need to have libcurl, libxml2, gtk2 and openssl installed on Ubuntu if you want to install certain packages, so also run these commands:
sudo apt-get update
sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libssl-dev
sudo apt-get install libxml2-dev
sudo apt-get install libgtk2.0-dev
Method 1 (recommended):
Another way that worked for me is to add the repository:
sudo add-apt-repository 'deb https://ftp.ussg.iu.edu/CRAN/bin/linux/ubuntu xenial/'
sudo apt-get update

Now you might get an error like this:
W: GPG error: https://ftp.ussg.iu.edu/CRAN/bin/linux/ubuntu xenial/ InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 51716619E084DAB9
W: The repository 'https://ftp.ussg.iu.edu/CRAN/bin/linux/ubuntu xenial/ InRelease' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: There is no public key available for the following key IDs:
51716619E084DAB9  

The solution is to add the key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys KEYID
where you have to replace KEYID with the key ID shown in the error. Marked in bold three lines above this line.
Now update and install.
sudo apt-get update
sudo apt-get install r-base 
sudo apt-get install r-base-dev


Method 2: 
sudo apt-get update
sudo apt-get install r-base

Download the jpeg62 dependency from here and run dpkg to install it.
sudo dpkg -i libjpeg62_6b2-2_amd64.deb

Download R Studio from here and run dpkg to install it.
sudo dpkg -i rstudio-xenial-1.1.453-amd64.deb


Method 3:
However, if you want the latest version (advisable if you plan to install packages like arules) or you want to upgrade the version installed above, follow this:
sudo gedit /etc/apt/sources.list
Enter this line in the sources.list file (substitute the right Ubuntu version. Xenial is for Ubuntu 16.04): deb http://cran.rstudio.com/bin/linux/ubuntu xenial/
sudo apt-get update
sudo apt-get install r-base
