title: resize and adjust the heatmap in heatmap.2
body: <p>I've generated a heatmap like this: 
  <img src="https://i.stack.imgur.com/QwKXC.jpg" alt="enter image description here"></p>
  
  <p>The X-axis and Y-axis labels don't show completely. 
  My code is here:</p>
  
  <pre><code> heatmap.2(x,col=blueyelred,colsep=c(1:6),rowsep=(1:62), 
             sepwidth=c(0.05,0.05), sepcolor="white", trace="none",
             Rowv=F,Colv=F, scale="none", dendrogram="none",key=F, 
             lhei = c(0.05,5),margins=c(1,8))
  </code></pre>
  
  <p>Is there any way to adjust it.</p>
  
  <p>Thanks!
  Cam</p>
