[Rd] specials issue, a heads up

[Therneau, Terry M., Ph.D.]

I recently had a long argument wrt the survival package, namely that the following code 
didn't do what they expected, and so they reported it as a bug

   survival::coxph( survival::Surv(time, status) ~ age + sex + survival::strata(inst), 
data=lung)

a. The Google R style guide  recommends that one put :: everywhere
b. This breaks the recognition of cluster as a "special" in the terms function.

I've been stubborn and said that their misunderstanding of how formulas work is not my 
problem.   But I'm sure that the issue will come up again, and multiple other packages 
will break.

A big problem is that the code runs, it just gives the wrong answer.

Suggestions?

Terry T.
