title: How can I change the font size of the labels in corrplot's lengend, in R?
body: <p>I would like to change the size of the 1 to -1 labels in the scale that appears alongside a call to <code>corrplot</code>, but am unsure what parameter to pass to accomplish this.</p>
  
  <p>An example call would look like </p>
  
  <pre><code>corrplot(data, method="pie", cex=2)
  </code></pre>
  
  <p>Some reasonable guesses on my part, which did not work, include:</p>
  
  <pre><code>cex=2 (errors/warnings, no effect)
  cex.xlab=2 (errors/warnings, no effect)
  cex.legend=2 (errors/warnings, no effect)
  cex.axis=2 (sets axis labels of main plot 2x size, no effect on legend text)
  </code></pre>
