  </code></pre>
  
  <p>I also tried </p>
  
  <pre><code>install.packages(c('reshape2','scales'))
  </code></pre>
  
  <p>Get the error that <code>plyr</code> is not available.</p>
  
  <p>I also upgraded Ubuntu and also reinstalled latest version of R and updated the packages using <code>update.packages(checkBuilt=TRUE)</code>.
  But, nothing worked. What can I do?</p>
