Here is one rationale for the change, which was useful for my understanding
This arises in the survival package in the survexp function:
survexp <- function(formula, data, weights, subset, na.action,....
ratetable=survexp.us)
The argument has been changed to survival::survexp.us, soon to be uploaded to
CRAN.
Assume that a user has an object named "survexp.us" in their working data, and calls
survexp without providing a ratetable arguement. Should they get the package default or
their own object? I'd vote for the first, but the current behavior is the latter. This
was presented to me as "fixing a bug that has long been present, but we never noticed before."
Now, if the user adds "ratetable=survexp.us" to the call they should get their own
object. I've always hated computer systems that ignore explicit direction, assuming they
know more than me.
