effects
component of the fit against the appropriate quantiles
of the normal distribution.
qqnorm(x, full=F, label, omit=NULL, ...)
TRUE
for a full normal probability plot
of the effects,
FALSE
for a half-normal plot
of the absolute values of the effects.
TRUE
,
in which case the user will be prompted to identify the points to label,
or to a single number,
n
,
in which case the
n
largest effects
(in absolute value) will be labeled.
"(Intercept)"
e.g.,
names(x$effects)[1] <- "*I*"
Graphical parameters may also be supplied as arguments to this function
(see
).
identify()
to label interesting points after the fact.
In the case of multiple responses or error strata,
the points from the last plot are returned.
effects
component from the fit
or of its absolute value,
plotted against the appropriate quantiles of the normal distribution.
In the case of multiple response or multiple strata,
one plot will be produced for each separate set of effects.
Subtitle labels will be composed in this case identifying the response
and/or the stratum.
This function is a method for the generic function for class aov. It can be invoked by calling for an object x of the appropriate class, or directly by calling regardless of the class of the object.
