     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. Where relevant, the functions in car are
     consistent with na.action = na.omit or na.exclude.
