Hi I've been trying to color my heatmaps, first I found color brewer and wasn't thrilled with the options, then I found a thread of emails regarding this topic from Fri Sep 12 2003 - 20:05:41 Gregiry Warnes and then I came across "maPalette" is this function the same as the code from 2003? Can I simply use > my.pal <- maPalette(low="green", high="red", mid="black", k =69) > out<-heatmap(x, col = my.pal) and get the same results as with that long code? Thanks [[alternative HTML version deleted]]
