title: Removing x-axis label from dendrogram in r
body: <p>I use xlab="" to suppress the x-label but still get a 'sub-x-label' in my dendrogram. How can I remove this and remove any extra space under the dendrogram?   </p>
  
  <pre><code>require(graphics)
  
  hc &lt;- hclust(dist(USArrests), "ave")
  plot(hc,xlab="")
  </code></pre>
