[Rd] ::: inside the package

In some cases I have had difficulties to evaluate non-exported/hidden R functions from C code without ::: (inside the package). But that's a different story and not any serious problem at all. Probably there is also some easy workaround, but I haven't even tried to search for any other solutions as ::: works fine.
