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

        The generic functions `cbind' and `rbind' take a
        sequence of vector and/or matrix arguments and combine
        them as the columns or rows, respectively, of a matrix.

        If there are several matrix arguments, they must all
        have the same number of columns (or rows) and this will
        be the number of columns (or rows) of the result.  If
        all the arguments are vectors, the number of columns
        (rows) in the result is equal to the length of the
        longest vector.  Values in shorter arguments are recy-
        cled to achieve this length.

        When the arguments consist of a mix of matrices and
        vectors the number of columns (rosw) of the result is
        determined by the number of columns (rows) of the
        matrix arguments.  Any vectors have their values recy-
        cled or subsetted to achieve this length.

        The method dispatching is not done via `UseMethod(..)',
        but by C-internal dispatching.  Therefore, there's no
        need for, e.g., `rbind.default'.
