title: How to draw an empty plot?
body: <p>I need to make an empty plot. This is the best could I come up with.</p>
  
  <pre><code>plot(0, xaxt = 'n', yaxt = 'n', bty = 'n', pch = '', ylab = '', xlab = '')
  </code></pre>
  
  <p>Any simpler solutions? </p>
  
  <p>P.S.: completely empty, no axis etc.</p>
