[R] QQplot normally distributed

[John Fox]

Dear Kjetil,

Simulated point-wise confidence envelopes are available from qqPlot() only for studentized residuals from linear and generalized linear models. For an independent sample of observations, the confidence envelopes produced by qqPlot() are based on the standard errors of the order statistics for the reference distribution.

Best,
 John
