title: remove the outliers in bwplot
body: <p>I'm creating a bwplot{lattice} and I would like it not to display the outliers. Here is example code:</p>
  
  <pre><code>m &lt;- mtcars
  
  m$gear &lt;- factor(m$gear)
  m$vs &lt;- factor(m$vs)
  m$am &lt;- factor(m$am)
  
  bwplot(drat ~ gear | am + vs,
     data = m)
  </code></pre>
