Hi List, I want to show the heatmap of a correlation matrix using "heatmap.2", however always get this warning message (see below) and the column dendrogram is not showing.? It's not really a big deal, but curious how to suppress it and still let R show what I want to show (i.e. a symmetrical heatmap with dendrogram for both rows and columns).? I'm using gplots 2.7.4 and R2.10.1 on Win XP. Thanks! ################> heatmap.2(cor(matrix(rnorm(100),10,10)), symm=T, symbreaks=T, trace="none", density.info="none")Warning message: In heatmap.2(cor(matrix(rnorm(100), 10, 10)), symm = T, symbreaks = T,? : ? Discrepancy: Colv is FALSE, while dendrogram is `row'. Omitting column dendogram. _________________________________________________________________ The New Busy think 9 to 5 is a cute idea.
