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, it does not duplicate
capabilities in the basic distribution of R, nor in widely used packages.
Where relevant, the functions in car are consistent with na.action = na.omit
or na.exclude.
