Hi,
Does anyone know how I can specify the colors based on the data values in
heatmap?
I have values ranging from -4 to 25 and I want to specify colors as:
-4 = white
0 = white/snow
10 =darkblue
20 = red
25 = dark red
the command line that I am currently using is (which is close to what I want
but not exactly)
col=colorRampPalette(c("-5" = "white","5" =
"white", "10" = "darkblue", "20"
= "red"))(4)
can I get a smooth transition in heatmap colors from white to blue to red in
R?
Thanks!
