     Effects

     This package creates effect displays for various kinds of models,
     as explained in the references. Typical usage is
     'plot(allEffects(model))' or 'plot(allEffects(model), ask=FALSE)',
     where 'model' is an appropriate fitted-model object. Additional
     arguments to 'allEffects' and 'plot' can be used to customize the
     resulting displays. The function 'effect' can be employed to
     produce an effect display for a  particular term in the model, or
     to which terms in the model are marginal. See '?effect' and
     '?plot.eff' for details.
