body: <p>How can I find the 5 highest values of a column in a data frame </p>
  
  <p>I tried the <code>order()</code> function but it gives me only the indices of the rows, wherease I need the actual data from the column.  Here's what I have so far:</p>
  
  <pre><code>tail(order(DF$column, decreasing=TRUE),5)
  </code></pre>
