title: How to remove NaN in large list
body: <p>I'm trying to remove my <code>NaNs</code> in a very large list.
  Removing <code>NAs</code> is quite easy with </p>
  
  <pre><code>My.List[!is.na(My.List)]
  </code></pre>
  
  <p>But using</p>
  
  <pre><code>My.List[!is.nan(My.List)]
  </code></pre>
  
  <p>is not an implemented method for lists (R-Error). </p>
  
  <p>Can you help me? Thanks!</p>
