title: Is there any way to use the Identify command with ggplot 2?
body: <p>In this case, everything is ok:</p>
  
  <pre><code>x &lt;- 1:10 
  y &lt;- x^3
  plot(x, y)
  identify(x, y)
  </code></pre>
  
  <p>But, using qplot there are some troubles:</p>
  
  <pre><code>x &lt;- 1:10 
  y &lt;- x^3
  qplot(x, y)
  identify(x, y)
  </code></pre>
  
  <p>Does anybody know a similar command or other way to label specific points in ggplot2 graphs?</p>
