Yes,
I believe I did something along your lines.
See the code snippet at the end of the email which sorts everything out
as far as I am concerned.
Cheers

Dear Hrishi,
I am almost there, thanks. The only small problem left is to convince
also the colorbar to plot the values I want.
Consider the small snippet at the end of the email: colors and numbers
inside the cells are OK, but the legend show
Lorenzo,
You can also use a custom colorscale using color.scale and the
cellcolors option of color2D.matplot:
pdf("test_color_scale_logcolor.pdf")
oldpar<-par( mar = c(4.5,5, 2, 1) + 0.1,
cex.axis=1.4,cex.lab=1.6,cex.main=1.6)
cellcolors <- color.scale(log(A),c(0.2,1),c(0.2,0.5),c(0,0))
color2D.
Lorenzo,
This is a bit ugly but should work. Instead of using plotrix's show.values,
use the text() command:
for(i in 1:5) {
for(j in 1:5) {
text(i-0.5,j-0.5,format(A[6-j,i],digits=3),col="white")
}
}
