title: Label outliers in an scatter plot
body: <p>I've plot this graphic to identify graphically high-leverage points in my linear model.

  <p>Given the variable "NOMBRES" of the data set which my model uses, I've tried to plot all the points of my graphic but it gets illegible. Here's the code I ran:</p>
  
  <pre><code>&gt; plot(hatvalues(tmodel),residuals(tmodel))
  &gt; text(hatvalues(tmodel),residuals(tmodel),labels=DSET$NOMBRES)
  </code></pre>
  
  <p>So I would like to plot just the points with leverage(hat value) above 0.05 using the label "DSET$NOMBRES".</p>
