[R] FW: partial residual plots

[Mark Difford]

Dwayne,

Sorry, I forgot about this: also look at ?ceres.plots, also in package car.

>From Prof. Fox's documentation: "Ceres plots are a generalization of
component+residual
(partial residual) plots that are less prone to leakage of nonlinearity
among the predictors."

Regards, Mark.
