title: order the coefficients by magnitude in multiplot
body: <p><a href="https://stackoverflow.com/questions/40197807/decreasing-coefficients-in-rs-coefplot?noredirect=1#comment67661855_40197807">Previous question</a> asked how the coefficients can be plotted in <code>coefplot</code> in descending order. The answer was to include <code>sort = 'magnitude'</code></p>
  
  <p>However, I then discovered that this method does not work when plotting multiple models using <code>multiplot</code>:</p>
  
  <pre><code>data(tips, package = "reshape2")
  mod1 &lt;- lm(tip ~ day + sex + smoker, data = tips)
  mod2 &lt;- lm(tip ~ day + sex + smoker + size, data = tips)
  multiplot(mod1, mod2, decreasing = TRUE, sort = "magnitude")
  </code></pre>
  
  <p>Is there a way to do this with <code>multiplot</code>? I realize it might not be straightforward. I just wonder if I am missing something.</p>
