title: I pointed the file.choose() command to a file titled "mytest.r". How do exit from this now?
body: <p>I am a novice trying to learn R using the swirl library. I entered the below command after which the screen just lets me type endlessly. </p>
  
  <pre><code>file.choose("mytest2.r")
  </code></pre>
  
  <p>Could someone help me understand what exactly is expected here and how to exit out of this? <code>mytest2.r</code> is just a blank file.</p>
