...ey should all be reflected in the normal qqline(). For instance: if I qqnorm() bimodal or uniform data I get a sigmoidal in which the qqnorm() points lie above the qqline() at -ve theoretical quantiles, and the qqnorm() points lie below the qqline() at +ve theoretical quantiles. Yet I expect such platykurtic distributions to go the other way (eg pg 117 in _Biometry_ Sokal & Rohlf, 3rd ed). The same thing with skewed data, I expect right skewed data to show a negatively accelerating shape, but qqnorm() curves upwards. Am I missing something, or is qqnorm() consistently heading in the wrong diirec...
