Note that your attachment was lost, so we don't know what your package code looks like. It's helpful to host your package sources somewhere publicly accessible (e.g. GitHub) to make it easier for others to access sources quickly from a web browser.
My best guess is that your 'init.c' is missing the recommended calls to R_registerRoutines() and R_useDynamicSymbols(). tools::: package_native_routine_registration_skeleton() (new in R 3.5.0, if I recall correctly) is very useful for auto-generating 'init.c' for you. See its associated help file for usage.
