title: R return corrplot as object
body: <p><code>corrplot</code> plots a correlation matrix, but it does not return a graphical object (grob)</p>
  
  <p>I would like to plot several correlation matrices on a single page. For normal plots, I would use <code>grid.arrange</code> from the <code>gridExtra</code> package. However since corrplot only prints and does not return an object, I can't see how to do this.</p>
  
  <p>Is there a workaround or a better alternative to <code>corrplot</code> ?</p>
