Hi Karl,

You can plot your palet based on whatever colorscheme you want i.e.
redgreen() or greenred(). If you want black omitted then maybe try building
a custom colorpanel(n, low, mid, high), where you specify your own mid point
color.

I see you already have some ordering set for your Rows and Cols.
Error in heatmap.2(data, Colv = Colv, Rowv = Rowv, col = plotcols, scale =
scale,  :

the dendrogram plotting is controled by the dendrogram arg. dendrogram =
c("both","row","column","none"), I'm not sure why this is not matching the
arguement correctly (suggest you post the actual code you are using).
but dendrogram="column" should work.

There is a good tutorial here -- see end of:
