[Rd] Questions about S4 style methods and generics

[Saikat DebRoy]

I have some questions about S4 style methods and generics.

First of all, is there any way of using default values for arguments
in the generics/methods? My own experiments show that such arguments
are always ignored. The green book seems to be silent on this
matter.

The second question is about using a non-trivial function body for
generics. Page 351 of the green book gives an example of this and the
documentation for setGeneric seems to suggest I should be able to do
this at least by using myDispatch=TRUE. However, the current
implementation seems to set the body of the generic definition to a
call to standardGeneric all the time. Is this a bug or a modification
of the green book description?

Thanks,

Saikat
