[R] Heatmap

[Eleftheria Dalmaris]

Hello all,

I have made the attached heat map without a problem.

On this heat map, the yellows are my high values and the oranges are my low
values. Is there a way to change that? Where the orange color is to have
the yellow and vice versa?

Thanks a lot,

Eleftheria

P.S.
In case is needed here is the code:
data_heatmap <- heatmap(data_matrix, Rowv=NA, Colv=NA, col =
heat.colors(256), scale="column",
cexCol = 1.5, cexRow = 0.5, margins=c(0.5,5))
