Install R under Ubuntu Jaunty (v9.04)

If installing from Ubuntu 'official' repository, search with 'CRAN' in Synaptic Package manager, and install components that you want.

Below guide is for installing R from 'third party' repository, which may gives newer release of R.

1. Add pubkey
   $ gpg --keyserver keyserver.ubuntu.com --recv D67FC6EAE2A11821
   $ gpg --export --armor D67FC6EAE2A11821 | sudo apt-key add -
   
   
2. Add repositories
   
   • Method 1:
     System >> Administration >> Software Sources
     Fill in 'deb http:///bin/linux/ubuntu jaunty/'
     where can be such as 'http://cran.opensourceresources.org/ '
     
     
   • Method 2:
     $ sudo gedit /etc/apt/sources.list
     add 'deb http:///bin/linux/ubuntu jaunty/'
   
   
3. Install complete R system
   $ sudo apt-get update
   $ sudo apt-get install r-base
   
   Users who need to compile R packages from source [e.g. package maintainers, or anyone installing packages with install.packages()] should also install the r-base-dev package:
   $ sudo apt-get install r-base-dev
