title: Why is the viewer window in R studio busy when I read in a data.frame?
body: <p>I started a new session in R Studio. When I read in a <code>data.frame</code> from a <code>.csv</code> file, the "Viewer" window is busy and does not stop. Does anyone know what the cause might be and more importantly, how to prevent it, please?</p>
  
  <p>The environment is completely empty, I have no packages loaded and the only code I am using is:</p>
  
  <pre><code> mydata &lt;- read.table("~/Desktop/mydata.csv", header=TRUE, sep=",", 
        check.names=FALSE)
  </code></pre>
  
  <p>Re-installing R Studio on my Mac did not help either.</p>
  
  <p>I am unable to use R at all this way :(</p>
  
  <p>Thank you.</p>
