title: How to resize a plot (not the window) in R?
body: <p>Hopefully a simple question for the community tonight: 
  I'm creating a boxplot with particularly long xlabels, which are rotated. The issue I'm running in to is that regardless of what plot window size I set using </p>
  
  <pre><code>dev.new(width=999, height=999)
  </code></pre>
  
  <p>The plot itself stretches to fill the window,and the x labels are chopped. 
  <strong>How do I resize the plot itself, regardless of window size?</strong>
  My current plotting code is:</p>
  
  <pre><code>boxplot(mean_density~Landscape*category,ylab="Mean density",las=2,data=data1C)
  </code></pre>
  
  <p>The reason the X labels are so long is because of that landscape*category piece. </p>
  
  <p>Thanks in advance!!</p>
