Hi, Take a look at the heatmap.2 function in the library gplots, and the brewer.pal in the library RColorBrewer. With this combination you have a far bigger flexibility on the colors and the output, plus you get a colorcoded legend. There used to be a bug in that function distorting the legend when breaks with unequal intervals were used, but I've adapted the function myself to work also in that case. If you need it, feel free to contact me.
