title: Position-dodge warning with ggplot boxplot?
body: <p>I'm trying to make a boxplot with ggplot2 using the following code:</p>
  <pre><code>p &lt;- ggplot(
        data,
        aes(d$score, reorder(d$names d$scores, median))
       ) +
         geom_boxplot()
  </code></pre>
  <p>I have factors called names and integers called scores.</p>
  <p>My code produces a plot, but the graphic does not depict the boxes (only shows lines) and I get a warning message, &quot;position_dodge requires non-overlapping x intervals.&quot; I've tried to adjust the height and width with <code>geom_boxplot(width=5)</code>, but this does not seem to fix the problem. Can anyone suggest a possible solution to my problem?</p>
  <p>I should point out that my boxplot is rather large and has about 200 name values on the y-axis). Perhaps this is the problem?</p>
