title: R: how to label the x-axis of a boxplot
body: <pre><code>     apple=c(1,2,3,4,5)
       banana=c(5,4,3,2,1)
       watermelon=c(4,5,6,7,8)
       boxplot(apple, banana, watermelon)
  </code></pre>
  
  <p>If I were to plot this, the x-axis of the boxplot is labeled as 1, 2 and 3. How can I change those to "apple", "banana", and "watermelon," respectively? <code>xlab=</code> labels the entire axis, but not the individual boxplots. Which command/option should I use?</p>
