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? Thank you,

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. Jim

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,

Xavier, Perhaps this would be of help, you could use it as a starting point: http://www.cs.princeton.edu/~mimno/factor-analysis.R This page provides a function for Hinton diagrams. -Peter Op 7-12-2011 17:45, Xavier Fern?ndez i Mar?n schreef:

Just for future reference and searches, the Hinton diagram has been implemented in the color2D.matplot function of the plotrix package. Thank you Jim.
