It is normal to report smooth curves via plots of smooth curves. There are examples for ppr in MASS4 p.241 (referenced on the help page). This is done by the plot() method.
Please do consult the references in the documentation: those who very carefully documented these tools put them there because they do give additional information.

In what sense do you claim it to be `undocumented'? Methods should do what the generic is documented to do, and that is the case here. [...] -- Brian D.
