I don't know Heatmap_plus, but other heatmap functions (such as
heatmap.2 from gplots) usually have an argument called "distfun",
used to calculate the distance between rows/columns. I think I've
sometimes used something along the lines of
> heatmap.2(data, distfun=function(x) as.dist(1-cor(t(x)), ...)
but I can't remember exactly.
