[BioC] heatmap-suppress col reordering/dendrogram?

[Ann Hess]

Using the heatmap function, is there a way to suppress the column 
reordering and column dendrogram?  I have five time points and I want to 
keep them in order!  I have tried the following commands, but still get 
reordered columns:

 	heatmap(x, Colv=FALSE...
 	heatmap(x, Colv=NULL...

Also, is there a way to suppress the row dendrogram, but still reorder the 
rows according to some dendrogram?  I was hoping to gain space for my row 
labels by omitting the dendrogram.  I have tried the following command, 
but still get the dendrogram:

 	heatmap(x, Rowv=as.dendrogram(hc), keep.dendro=FALSE)
