qqplot from package stats to
be applicable to distribution and probability model objects. In this context,
qqplot produces a QQ plot of data (argument x) against
a (model) distribution.
Graphical parameters may be given as arguments to qqplot.

observations are ordered (as order(trafo(obs)).col.pch and col.lbl; if one-dim and NA all colors are

gets shorted/prolongated to length the data-symbols to be plotted.
Coordinates of this vector alpha.trsp with NA are left unchanged,
while for the remaining ones, the alpha channel in rgb space is set
to the respective coordinate value of alpha.trsp. The non-NA
entries must be integers in [0,255] (0 invisible, 255 opaque).x-quantiles lie

the ... argument, all arguments valid for

function, qqplot from package distr for
comparisons of distributions, and
qqbounds, used by qqplot to produce confidence
intervals.
