title: Change width of individual boxes in boxplot in R
body: <p><strong>How can I reduce the width of each individual boxplot in Base R?</strong></p>
  <p>I do not want to change the <em>relative</em> sizes of the boxplots, which I understand can be done with the <code>width</code> argument</p>
  <p>(this is not the same question as <a href="https://stackoverflow.com/questions/23418811/how-can-i-reduce-the-space-between-two-discrete-values-in-the-x-axis">this post</a>, which asks about removing whitespace)</p>
  <pre><code>boxplot(mpg ~ cyl,
          data=mtcars)
  </code></pre>
