        `medpolish' fits an additive constant-plus-rows-plus-
        columns model to the values given in `x' using Tukey's
        median polish procedure.

        Sweeping out for row and column effects continues until
        the proportional reduction in the sum of absolute
        residuals is less than `eps' or until the have been
        `maxiter' iterations.  The sum of absolute residuals is
        printed at each iteration of the fitting process.

        The value returned by `medpolish' is an object of class
        `medpolish'.  Printing and plotting methods are defined
        for this class, and can be invoked via the generic
        functions `print' and `plot'.

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

        An object of class `medpolish' with the following named
        components:

    overall: the fitted constant term.

        row: the fitted row effects.

        col: the fitted column effects.

   residuals: the residuals.

       name: the name of the dataset.
