Hi!
I'm displaying a contingency table with heatmap():
svm.predPix.tabla
svm.predPix CC DD LL NN NN2
CC 22 0 3 8 3
DD 0 27 0 1 0
LL 1 1 90 3 7
NN 2 0 1 11 4
NN2 0 0 5 1 20
heatmap(svm.predPix.tabla[5:1,], Rowv=NA, Colv=NA,col =
rev(heat.colors(32)), scale="column", margins=c(5,10))
and I'm happy with the plot except that I would like to have the actual
values displayed within each cell. Any help on how
to achieve this?

Hi Agustin,
I was going to send the code from color2D.matplot to display the values,
but it required so much modification that I would suggest:
library(plotrix)
color2D.matplot(svm.predPix.tabla,show.values=TRUE,axes=FALSE,
xlab="",ylab="")
axis(1,at=0.5:4.5,labels=rownames(svm.predPix.tabla))
axis(2,at=4.5:0.5,labels=colnames(svm.predPix.tabla))
