Typical usage is
plot(allEffects(model))
or plot(allEffects(model), ask=FALSE)
,
where model
is an appropriate fitted-model object.
Additional arguments to allEffects
and plot
can be used to customize the resulting
displays. The function effect
can be employed to produce an effect display for a
particular term in the model, or to which terms in the model are marginal.
See ?effect
and ?plot.eff
for details.
