title: R package installation in ubuntu
body: <p>Something of a newbie here.  I've been working in R for windows and have recently moved to ubuntu, ("Hardy Heron" I think).  I'm also not a linux guy.  Anyway.  I'm tring to install the "diptest" package.  I ran the command </p>
  
  <pre><code>install.packages("diptest") 
  </code></pre>
  
  <p>and the output is:</p>
  
  <blockquote>
    <p>Installing package(s) into ‘/home/smart/R/i486-pc-linux-gnu-library/2.6’
        (as ‘lib’ is unspecified)
    which is a little strange since I'm running R 2.12.1.  And then it hangs.</p>
  </blockquote>
  
  <p>Also, if I call <code>library("diptest")</code> it says that I need to reinstall the package because it is built for R 2.6.  Is the process for reinstalling different than <code>install.packages</code>?  Thanks.  Sorry to ask such a simple question.</p>
