I have tried the color2D.matplot() function and it works fine for what I
need now (checking matrices for my own use). However, it would be great if
R can have Hinton diagrams, and color2D.matplot would probably be the best
way to start. So I will appreciate very much if you can morph it.

Probably the single line to change will be the calls to hexagon() and
rect(), which will need some tunning. I will be glad to try to help.

Best,
