        coef(x, ...)
        coefficients(x, ...)

   AArrgguummeennttss::

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

        ...: other arguments.

   DDeessccrriippttiioonn::

        `coef' is a generic function which extracts model coef-
        ficents from objects returned by modeling functions.
        `coefficients' is an alias (`.Alias') for it.

   DDeettaaiillss::

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

   VVaalluuee::

        Coefficients extracted from the model object `x'.

   SSeeee AAllssoo::

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

   EExxaammpplleess::

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