title: Customizing metaMDS() plot
body: <p>I have created a NMDS plot using the 'vegan' package, like this:</p>
  
  <pre><code>y=metaMDS(data,type="p").
  plot(y)
  </code></pre>
  
  <p>Now I have this NMDS with a good spread of my points. However, I would like to add the graphics of the plot. I would like to give the points in the plot a different colour, depending on a categorical variable (the variable is called 'regio') in my dataset, which has two values (1 or 2).</p>
  
  <p>Is this possible? And if so, how?</p>
  
  <p>Best,
  Koen</p>
