          x: an object for which the extraction of model coef-
             ficients is meaningful.

        These are generic functions which extract model coeffi-
        cents from objects returned by modeling functions.  The
        abbreviated form `coef' is intended to encourage users
        to access object components through an accessor func-
        tion rather than by directly referencing an object
        slot.

        All object classes which are returned by model fitting
        functions should provide a `coefficients' method.
