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?
