Hi Schalk,
the heatmap function does not implement "two-way joining" as far as I know.
It clusters rows and columns independently.  However if you find or program
a method that implements two-way joining, you could use the row and column
ordering it returns in your heatmap using the Rowv and Colv arguments to
heatmap.
