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)) -------------- next part -------------- A non-text attachment was scrubbed...
