R help - Nov 2007 - Heatmap problem

Hi friends,

I used heatmap(as.matrix(y2),col=rainbow(256),scale = "column") to
generate the heatmap. But it did not show the code that which
color correspond the value. Is there any parameter for this in
heatmap()?

Thanks a lot!

Hi Allen,
If you want colors corresponding to the values with a color legend, have 
a look at color2D.matplot in the plotrix package.

Jim

Try Heatmap.2 in the gplots package.

Hi Allen,
