Hi. I would like to do 2 way hierarchical clustering (ie cluster genes and samples) and then plot a heat map to visualise if genes are up or down regulated in different samples, therefore I need to attach gene labels to the heat map and sample names and have an appropriate colour scheme. I would also like to run the clustering on median and/or mean centered data. Can anyone help me with this analysis.
