title: Sourcing script does not print any output to the console
body: <p>I am using Ubuntu inside Windows XP using VirtualBox, and I installed R properly. I am using a library called <code>psych</code> for this. The following is my code:</p>
  
  <pre><code>impact &lt;- read.table("stats1.ex.02.txt", header=T)
  class(impact)
  describe(impact)  
  </code></pre>
  
  <p>I am taking Statistics One course on coursera.org and the Prof gives this <code>txt</code> file to work with. When I run this in R, using <code>source("test.R")</code> (where <code>test.R</code> is the filename I gave), 
  nothing happens. What could be problem here ?</p>
