Heatmap color key with five different colors
I have the following code and not sure how to use it to display a heatmap with a color key displaying five different colors representing defined values: 

    hm <- heatmap.2(data_matrix, scale="none",Rowv=NA,Colv=NA,col = rev(brewer.pal(11,"RdBu")),margins=c(5,5),cexRow=0.5, cexCol=1.0,key=TRUE,keysize=1.5, trace="none")

Color key required:

    <0.3 (blue)

    0.3-1 (green)

    1-1.3 (yellow)

    1.3-3.0 (orange)

    >3.0 (red)

I would be happy if someone can help. Thanks!
