  </code></pre>
  
  <p>I tried the command: </p>
  
  <pre><code>WriteXLS("my matrix after i converted it to data.frame", "test.xls")
  </code></pre>
  
  <p>but I got this error:</p>
  
  <blockquote>
    <p>The Perl script 'WriteXLS.pl' failed to run successfully.</p>
  </blockquote>
  
  <p>I googled it but I couldn't find a solution.</p>
  
  <p>Thanks in advance. </p>
