How to deal with package conflicts

In my genridge package, I define a function ridge() for ridge regression, creating objects of class 'ridge' that I intend to enhance. In a documentation example, I want to use some functions from the car package. However, that package requires survival, which also includes a ridge() function, for coxph models. So, once I require(car) my ridge() function is masked, which means I have to use the awkward form below in my .Rd files. ridgemod<- genridge::ridge(...) I tried to detach survival, but that doesn't work:
> detach("package:survival")
Error: package ?survival? is required by ?car? so will not be detached
I don't see any solution to this, other than
(a) renaming my ridge() to something else -- don't want to do this
(b) use \dontrun{} for the examples that use car
Or, is there some other way?
Not really. I'd say the renaming is the preferred way to go, but you might also be able to convince Terry Therneau (survival author) to make ridge() a generic, so your method is called for your objects, and his is called for others. Duncan Murdoch
