Hi, Is it possible to create a heatmap for say a 3x3 matrix of data where every color is pre-assigned? I can easily create a matrix of hex colors but when I try to use that matrix as the parameter for the 'col' option it doesn't work. If it's possible to just display a matrix of hex colors that would work as well thanks

Hi,
It's easy with ggplot2,
cols = matrix(c("#F7FBFF", "#DEEBF7", "#C6DBEF", "#9ECAE1", "#6BAED6",
"#4292C6", "#2171B5", "#08519C" ,"#08306B"), ncol=3)
library(ggplot2)
m = melt(cols)
qplot(factor(X1),factor(X2),data=m, fill=value, geom="tile") +
scale_fill_identity()
HTH,
