[BioC] Heatmap without using clustering result

[michael watson (IAH-C)]

Set both Rowv and Colv arguments to NULL and this should turn off clustering and just draw the heatmap

Hie, 

I use heatmap() for expression data.
my data set is already ordered by Mfuzz clustering.

If I use  my heatmap on my ordered.data.set, I get a beautiful heatmap reclustering by hclust.
 
by consequently, I have 2 possibility.
1. desactive hclust () in heatmap(): like this , I get a heatmap of my ordered.data.set without ordering by hclust()

2. integrate mfuzz, in heatmap function ( heatmap ( eset, hclust = function(x) mfuzz)

After severals tries et prospection on Internet, I need your help

Greg
