When you use the scaling capabilities of heatmap.2, the
resulting plot heatmap shows a legend that says
"Column Z scores" or
"Row Z scores".
The scaling looks as though the values have been normalized
to SD units.
z = (x - mean)/sd
Is this what heatmap.2 means by a Z score?
I am finding it tricky to reproduce their results using
the z value above.
