title: csv read inserts an 'X' column to my loaded dataframe in R..?
body: <p>Sometimes when I load a csv using read.csv I get an extra column called X with a sequential row count as the first column. I have to remove it each time.</p>
  
  <p>Does anyone know why this happens..?</p>
  
  <pre><code>X   Day   Who
  1   Tue   Bob
  2   Wed   Dan
  3   Thur  Joe
  </code></pre>
