[R] Multiple methods in models

The model specification formula language introduced in Chambers and
Hastie potentially handles rather complex models. Typically the user
specifies the model and in a separate argument specifies the method. For
example, one specifies a general linear model with glm(formula,family).
But with a complex model, one may want to use different methods to
compute different parts of the model. This seems to imply either
extending the formula language to integrate method specification as part
of the model specification or extending the separate method argument
(family in the case of glm) to include multiple methods along with a way
to relate them to different parts of the model.
I've looked to see if any packages do such a thing and have found none.
I've also looked through several documents on R without success.
Does anyone know of a package, document, or other thing in R-land that
does something like this?
