gqqnorm | R Documentation |
qqnorm is a generic function the default method of which produces a normal
QQ plot of the values in y
. qqline
adds a line to a
“theoretical”, by default normal, quantile-quantile plot which passes
through the probs
quantiles, by default the first and third quartiles.
qqplot
produces a QQ plot of two datasets.
Graphical parameters may be given as arguments to gqqnorm
,
gqqplot
and qqline
.
