Arguments
x
A list with components containing the residuals, the relevant
probabilities, the predictors, and the observations, as returned
by resid.mix(). When plotting against fitted values,
it is probably better to used the standardized residuals,
i.e
vs.fit
Logical argument. If TRUE the residuals are plotted versus the
fitted values.
whichx
Indicates which predictor to plot against if there is more than
one; i.e. indicates which column of the x matrix to use. If vs.fit
is TRUE, whichx is ignored.
shape
The shape of the plotting symbol; possible values are "disc",
"square", and "diamond". Partial matching is used so only
the first few letters need be given.
ngon
The "disc" shape is actually a regular polygon; ngon specifies
how many sides it should have; ignored if shape is not equal
to "disc".
size
A scale factor to change the absolute sizes of the plotting
symbols; values larger than 1 make the symbols larger; values
less than 1 make them smaller.
xlab
The x label for the plot; defaults to "x".
...
Additional arguments to be passed to the polygon function which
actually draws the plotting symbols.
