Description: Provides additional data sets, methods and documentation
        to complement the 'vcd' package for Visualizing Categorical
        Data and the 'gnm' package for Generalized Nonlinear Models. In
        particular, 'vcdExtra' extends mosaic, assoc and sieve plots
        from 'vcd' to handle 'glm()' and 'gnm()' models and adds a 3D
        version in 'mosaic3d'.  Additionally, methods are provided for
        comparing and visualizing lists of 'glm' and 'loglm' objects.
        This package is now a support package for the book, "Discrete
        Data Analysis with R" by Michael Friendly and David Meyer.
