How To Add Additional Panes To A Clustering Heatmap Plot Created With R

Question

[Jonathan Crowther]

Hi Folks,

I am performing Hierarchical Clustering in R and wish to add two additional panes into the heatmap to indicate two things: 1. The subtype relating to the sample 2. An activity value which is scaled from 0-8

I have been looking into RowSideColors and I can manage to get the display I wish but instead of highlighting the subtypes it simply colors each sub Cluster! something along the lines of this (Image a) with the legend

Have you read How Do I Draw A Heatmap In R With Both A Color Key And Multiple Color Side Bars? which describes how to add multiple color side bars. You can add any number of color side bars which highlight row/columns in any arbitrary way.
