title: Upgrade R on Kubuntu 14.4 LTS
body: <p>How can I upgrade my R installation on Kubuntu 14.4 LTS from 3.0.2 to the current 3.2.4?</p>
  
  <p>Something like</p>
  
  <pre><code>sudo su
  echo "deb http://www.stats.bris.ac.uk/R/bin/linux/ubuntu trusty/" &gt;&gt; /etc/apt/sources.list
  apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
  apt-get update
  apt-get upgrade
  </code></pre>
  
  <p>or a variation of this won't work - R will stay at 3.0.2. I tried replacing <code>trusty/</code> with <code>wily/</code>, but that did not change anything either.</p>
