coef is a generic function which extracts model coefficients
from objects returned by modeling functions. coefficients is
an alias for it.

Usage

coef(object, ...)
coefficients(object, ...)

Arguments

object

an object for which the extraction of model coefficients is
meaningful.

...

other arguments.

Value

Coefficients extracted from the model object object.For standard model fitting classes this will be a named numeric vector.
For "maov" objects (produced by aov) it will be a matrix.

Details

All object classes which are returned by model fitting functions
should provide a coef method or use the default one.
(Note that the method is for coef and not coefficients.)

Class "aov" has a coef method that does not report
aliased coefficients (see alias).
