R Documentation

Four types of residual plots for linear models.

Description

Four types of residual plots for linear models. The first three are redesigns of
plots that stats:::plot.lm presents.
The first two show the positive residuals in col[2] and the
negative residuals
in color col[1]. The third and fourth use color col[1].
The fourth is based on an S-Plus
panel that R doesn't provide.

Vector of color names. Only the first two are used.
If not specified, then
trellis.par.get("superpose.symbol")$col[1:2] is used.

main

standard main title for plots.

ylim

standard lattice argument.
It is used as specified for the residVSfitted, diagQQ, and
diagplot5new plots. For the scaleLocation plot, the
ylim is modified to c(0, max(abs(ylim))). The main reason
for using the ylim argument is to allow visual comparison of
the residuals for two different models on the same scale.

...

Other arguments, currently ignored.

Details

The trellis plots from the four functions residVSfitted,
scaleLocation, diagQQ, diagplot5new
are displayed on the current device in a coordinated display.

Value

A list of three trellis objects is returned invisibly, the first
contains the result of residVSfitted and
scaleLocation together. The second diagQQ,
and the third diagplot5new.
