Order of rows in heatmap?

Question

Take the following code:

 heatmap(data.matrix(signals),col=colors,breaks=breaks,scale=\"none\",Colv=NA,labRow=NA)

How can I extract, pre-ca

Answer 1

I agree with Jesse. For your problem take a look at the Rowv, distfun and hclustfunarguments of the heatmap function. For more choices the functions heatmap.2 in the gplots package, heatmap_plus in the Heatplus package and pheatmap in the pheatmap package could be of some use.
