        ...: objects to which `extract' will be applied. Gener-
             ally these will be model components, such as
             `corStruct' and `varFunc' objects.

    extract: an optional extractor function. Defaults to
             `coef'.

   DDeessccrriippttiioonn::

        The extractor function is applied to each object in
        `...', with the result being converted to a vector. A
        `map' attribute is included to indicate which pieces of
        the returned vector correspond to the original objects
        in `...'.

   VVaalluuee::

        a vector with all elements, generally coefficients,
        obtained by applying `extract' to the objects in `...'.
