title: r heatmap.2 colsep as vector
body: <p>I want to draw a heatmap, using heatmap.2(), in which I want to define colseps in several different colors.<br>
  I have tried specifiyng sepcolor by concatenation: </p>
  
  <pre><code>heatmap.2 (as.matrix(order_by27_T[rowsToDraw,]), Rowv=FALSE, Colv=FALSE,               dendrogram="none", col=hmColors, breaks=seq(0,1,(1/120)), trace="none", colsep=c(60,120,180), sepcolor=c("white","pink","green"))      
  </code></pre>
  
  <p>Further, I tried to create a character vector specfiying the desired colors in the desired order and to assign this vector to sepcolor:  </p>
  
  <pre><code>sepColour&lt;-c("white","pink","green")
  heatmap.2 (as.matrix(order_by27_T[rowsToDraw,]), Rowv=FALSE, Colv=FALSE, dendrogram="none", col=hmColors, breaks=seq(0,1,(1/120)), trace="none", colsep=c(60,120,180), sepcolor=sepColour)      
  </code></pre>
  
  <p>In both cases, all there seprators defined were green (the last element of the vector).<br>
  Is what I'm trying to do possible at all?  </p>
  
  <p>thanks in advance  </p>
