To save you some time: I'm pretty sure that you can't actually do that
with the heatmap (or heatmap.2) function. It will hog the entire
graphics device for itself.

Maybe you can use some other tool (like Illustrator, for example) to
stitch heatmaps together after you save them?

There are other ways to plot heatmaps, like using "levelplot" from
lattice, as well geom_tile with ggplot -- I wonder if you can rig
those plotting tools up to get the graph you want? (Not sure).
