Dear colleagues, I am working with a matrix (like a matrix of gene expression) and I have done a hierarchical clustering of genes, and want to plot it using a heatmap. My problem is that the heatmap reorders also the columns (not only the genes), and I don't want the columns to change their order. How can I solve this problem??? Thanks in advance, Federico

Hi Federico, You can take a look at the help for the heatmap function with ?heatmap. Colv is the argument you're looking for. Colv=NA will suppress any dendrogram for the columns. Most of the other heatmap functions should have this argument as well.
