Error in heatmap.2(exprs(esetSel), col = topo.colors(75), scale = "none",  : 
  'ColSideColors' must be a character vector of length ncol(x)

Kindly help me regarding above error during construction of heatmap.

Thanks

Well, the error message seems to tell you what's wrong. Have you looked at 'patientcolors' to check it that contains what you think it does?

On another point, using topo.colors for an expression heatmap doesn't seem a good choice to me. Since you're apparently using the limma package, you could try:

coolmap(exprs(esetSel))
