+models and return the result as tidy data frames.  These data frames are ready
+to use with the @code{ggplot2} package.  Marginal effects can be calculated
+for many different models.  Interaction terms, splines and polynomial terms
+are also supported.  The two main functions are @code{ggpredict()} and
address@hidden()}.  There is a generic @code{plot()} method to plot the
+results using @code{ggplot2}.")
