Hello Bioc Users,
I am having a hard time understanding why heatmap.2 uses row (or column)
Z-score instead of directly plotting logFC values? Based on the formula
for calculating Z-score, I understand that it is used for scaling or
smoothing. But, isn't it the same when using logFC. Please correct if I
am wrong. I really appreciate if anyone can give me a clear explanation.
Sorry for asking a silly question. I
