title: Changing the x-axis labels of a ggplot histogram
body: <p>I have the following dataset (edited for readability): </p>
  
  <pre><code>chol &lt;- read.table(url("http://assets.datacamp.com/blog_assets/chol.txt"), header = TRUE)
  </code></pre>
  
  <p>And I am creating a histogram of the data doing:</p>
  
  <pre><code>ggplot(data=chol, aes(chol$AGE)) + geom_histogram()
  </code></pre>
  
  <p>For a particular example I would like to change the x-labels however. </p>
  
  <p>Any thoughts on how I can pull this of?</p>
