title: corrplot function | Method is not a graphical parameter
body: <p>I've been using the corrplot function, and it has worked fine until this morning. Note: I did update Anaconda.</p>

  <p>Here is a screenshot of the code (which worked fine yesterday</p>

  <p>Essentially, I have the following code:</p>
  <pre><code>corrplot(cor(fattrain[ , 1:18]), method = &quot;pie&quot;, type = &quot;lower&quot;)
  </code></pre>
  <p>The error that I get is:</p>
  <pre><code>&quot;Method is not a graphical parameter&quot;
  </code></pre>
  <p>Why is this so? The code worked fine, yesterday? I've made no changes to the data/data types.</p>
