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. -levi
