Hinton Diagram for a matrix of weights

Jim Lemon vas escriure el dia dj, 08 des 2011:

The Hinton diagram looks fairly close to an image plot, or the 
color2D.matplot function. The difference is that the area of the squares 
in the Hinton plot are proportional to some value rather than the color, 
which indicates the sign of the value. If you have no luck finding this, 
I think I could easily morph color2D.matplot into a Hinton diagram 
function.

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,
