title: R: read.csv adding sub-script "X" in header
body: <p>I have a data frame that has headers as this</p>
  
  <pre><code>Name  0x1  1x2
  </code></pre>
  
  <p>read.csv changes the header to be </p>
  
  <pre><code>Name X0x1 X1x2
  </code></pre>
  
  <p>Is there a way, where this can be avoided?</p>
  
  <p>Thanks.</p>
