Hi:
I am trying to plot the most significant genes. I have 3 different
sample types and 4 replicates each. Could anyone suggest how do I get
the matrix of fpkm values that was plotted in csHeatmap function.

> diffGeneIDs <- getSig(cuff,level="genes",alpha=0.001)
> diffGenes<-getGenes(cuff,diffGeneIDs)
>h<-csHeatmap(diffGenes,cluster='both')


the heatmap gene names are not visible. I want to get the matrix for h
and plot heatmap using another heatmap function.
How do I get the matrix for h.

thanks
Adrian
