[BioC] Generating heatmap of 110x3200 samples

[Florian Hahne]

Hi Ruppert,
if I get you right you have an ExpressionSet for which both rows and  
columns have been rearranged according to some clustering. So why not  
do something like

image(t(exprs(foo)))

As for the dots: are there any NA values in your data? My first guess  
is that those are your white dots
