title: Recenter heatmap.2 in R
body: <p>I used following code to generate a heatmap using heatmap.2 of R. key="F" gets rid of color key at the top. However the plot does not rescale leaving a blank space on the place previously occupied by the colour key. How do I recenter the plot by getting rid of the blank space at the top?</p>
  
  <pre><code>dImp_heatmap &lt;- heatmap.2(dSet_matrix, Rowv=NA, Colv=NA, col = cm.colors(20), dendrogram="none",trace="none", key="F",margins=c(1,8),colsep=c(1:6),rowsep=(1:62),sepwidth=c(0.05,0.05), sepcolor="white", cellnote=round(dSet_matrix,digits=2),notecol="black",notecex=0.7,scale="column")
  </code></pre>
