[BioC] heatmap.2 Z scores

[Thomas Hampton]

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.


Best,

Tom
