Hackles down, Rolf... most documentation can benefit from the perspective of a new user. It would be helpful to link the mention of pp3 to the the pp3 function via hyperlink to help clarify what this argument is supposed to be.
Abby, FWIW I tend to recommend reading the vignettes before trying to absorb the function documentation... having a bird's-eye-view of how the package works will always make the function documentation easier to follow.
