title: duplicate 'row.names' are not allowed error
body: <p>I am trying to load a csv file that has 14 columns like this:</p>
  
  <pre><code>StartDate, var1, var2, var3, ..., var14
  </code></pre>
  
  <p>when I issue this command:</p>
  
  <pre><code>systems &lt;- read.table("http://getfile.pl?test.csv", header = TRUE, sep = ",")
  </code></pre>
  
  <p>I get an error message.</p>
  
  <blockquote>
    <p>duplicate row.names are not allowed</p>
  </blockquote>
  
  <p>It seems to me that the first column name is causing the issue. When I manually download the file and remove the <code>StartDate</code> name from the file, R successfully reads the file and replaces the first column name with <code>X</code>. Can someone tell me what is going on? The file is a (comma separated) csv file.</p>
