If you can, please turn off the HTML formatting in your email: it makes it quite hard to read.
I don't really know what you mean by a 3D heatmap: can you point to any examples of such figures online? You might be thinking of something like persp gives; try example(persp) (or example(persp3d) in the rgl package).
