Reverse color palette

[Yu Wai Chen]

Dear colleague,

How can I use the bwr.colors palette in the reverse order, i.e. red for negative; blue for positive, e.g. in plot.dmat? Thanks a lot.

The R base rev() function should do the trick. But in plot.dmat(), the input color palette is a function. So, something like:

plot.dmat(d, color.palette=function(n) rev(bwr.colors(n)))

Thanks a lot!

This is resolved.
