Hi, Rabe.

Try the heatmap() function (assuming you are asking about making a
picture).  Also, consider searching the email archives.  You'll
probably want to filter your genes first, as clustering all the data
is not likely to be a useful exercise.

If, instead, you want to do clustering (and not just make a picture),
try help.search('clustering').
