## Companion to Applied Regression

This package accompanies J. Fox, An R and S-PLUS Companion to Applied Regression,
Sage, 2002.
The package contains mostly functions for applied regression, linear models, and
generalized linear models, with an emphasis on regression diagnostics, particularly
graphical diagnostic methods. There are also some utility functions.
With some exceptions, I have tried not to duplicate capabilities in the basic distribution of R,
nor in widely used packages. Some of the functions in car will use functions
in the MASS package, if it is present; the subsets function graphs
objects produced by the regsubsets function in the leaps package. Where relevant, the functions in
car are consistent with na.action = na.omit or na.exclude.
