title: read.table reads "T" as TRUE and "F" as FALSE, how to avoid?
body: <p>I have a file with the data <code>c("A","T","B","F")</code>. </p>
  
  <p>When I use:</p>
  
  <pre><code>read.csv(myfile,header=F,stringsAsFactors=F)
  </code></pre>
  
  <p>R interprets character <code>T</code> as <code>TRUE</code> and <code>F</code> as <code>FALSE</code> </p>
  
  <p>Am I doing anything wrong?</p>
