Hi all,
I am trying to plot two pearson correlation coefficient matrices on one
heatmap using heatmap.2. I combined two matrices as following
A = [0.8 0.9;
0.75 0.95]
B = [0.82 0.87
0.94 0.74]
combined = [0.8 0.9 0 0;
0.75 0.95 0 0
0 0 0.82 0.87
0 0 0.94 0.74]
heatmap.2(combined,distfun=function(c) as.dist(1-c),hclustfun=function(c)
hclust(c,method="average"), race="none",
col=greenred(75),trace="none",dendrogram ="column")
The resultant heatmap having a scale from 0 to 1. I want to ignore the zero
elements in the combined matrix and display them in black. Also, I want the
scale to be greater than 0.7. I looked at the heatmap.2 webpage, but did not
have a clue. Could anybody help me? Thank you in advance.
Wendy
