Extract Model Coefficients

Description:

     `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.

Details:

     All object classes which are returned by model fitting functions
     should provide a `coef' method.  (Note that the method is `coef'
     and not `coefficients'.)

Value:

     Coefficients extracted from the model object `object'.

See Also:

     `fitted.values' and `residuals' for related methods; `glm', `lm'
     for model fitting.

Examples:

     x <- 1:5; coef(lm(c(1:3,7,6) ~ x))
