Hi Ricardo, This might be what you want (say your data frame is called my.df): library(plotrix) color2D.matplot(my.df,c(1,0),c(0,0),c(0,1)) text(rep(0.5:13.5,5),rep(seq(4.5,0.5,by=-1),14), unlist(my.df),col=white) and in fact it looks so neat that I might add it as an option.

jim holtman[EMAIL PROTECTED] 24/11/2006 23:21 If you data is a matrix, then try: image(1:5, 1:14, data.rect) text(row(data.rect), col(data.rect), data.rect) Thanks, Jim. It works great and perfectly fill my requirements. I better understand now how text() works. By the way, there is a line at the bottom of your message reading What is the problem you are trying to solve?, is this a kind of motto or are you asking me what I am trying to solve? :-) Thanks!

Jim Thanks, Jim! Once the original problem was solved by using image(), your plotrix() package is of major interest to keep improving this kind of graphics!

Please, allow me to try to use this method from now on!
