Hi, One of the features of heatmap is to set Colv or Rowv to NA if I don't wont to perform clustering on columns or rows respectively. This option does not exist in heatmap_2. Is there another way to show columns or rows cluster solely? Thanks, Ron

Colv = Vector, Rowv = Vector, ... The most recent version of heatmap_2 seems to have a problem with this though (or I am having a problem understanding the command syntax). This did work in R 2.2.1 and it does not in R 2.3.1. -- Bye, Marc Saric
