Give a user the ability to change a function in my R package

I am currently creating an R package and have the following issue. The package has one R routine, say aR, and two Rcpp routines, say bC and cC. Both aR and bC call cC. I would like the user to be able to create their own version of cC.

One solution would of course be to simply "open" the code of the three routines so a user can replace cC and just reinstall the package, but the actual package contains almost 20 routines and I don't want to make most of these visible to the user.

I tried the following already:

environment(newcC) <- asNamespace('packagename')
assignInNamespace("cC", newcC, ns = "packagename")

and that works for aR, it now runs cC instead of newcC. But it does not work with bC, it keeps using the original routine cC.

IceCreamToucan's suggestion to simply make cC an argument works just fine, so thanks!
