   AArrgguummeennttss::

     object: list; typically, the result of a model fitting
             function such as `lm'

   set.sign: logical ~~Describe `set.sign' here~~

   DDeessccrriippttiioonn::

        Returns (orthogonal) effects from a fitted (general-
        ized) regression model.  In case of a full rank n * p
        `model.matrix', the first p effects correspond to coef-
        ficients and the remaining n-p ones to residuals.

   VVaalluuee::

        A (named) numeric vector of the same length as `residu-
        als'.  The first p values are labeled according to the
        corresponding coefficients, the remaining ones are
        unlabeled.

        The result currently has `class' `"coef"'.
