Jean, I have attached an example set of data. The code for reading and manipulating it before display as a heatmap is as follows:
Apo_Mut<-read.table("Example_Data.txt") require(cluster) blah <- agnes(as.matrix(max(Apo_Mut)-Apo_Mut)) blah2<-as.hclust(blah) LabsDend <- as.dendrogram(blah2) RowCol<-order.dendrogram(LabsDend) This should put my previous code into context. The way the heatmap is set-up, the labels appear in the graphic, just not when it gets output to the pdf.
