Hinton Diagram for a matrix of weights

Hello,

Although I have used a general search engine, r-seek, and browsed CRAN for
contributed packages and R Gallery, I have not been able to find an
implementation of Hinton Diagrams for representing weighting matrices using
R.

Does anyone knows a way of plotting weighting matrices in R?

Hi Xavier,
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.
