I'm a bit confused about this as well. My impression is that the only
reason to register functions is so that *other* packages can call them. If
you do not want to make them available, you don't need to register them. Or
I could have that complete wrong.

THK

If you don't want to register anything, this snippet placed in init.c will
get you past CRAN checks currently:

#include <R.h>
#include <Rinternals.h>
#include <R_ext/Rdynload.h>
R_CallMethodDef callMethods[] = {{NULL, NULL, 0}};
R_CMethodDef cMethods[] = {{NULL, NULL, 0}};
void
R_init_myLib(DllInfo *info)
{
R_registerRoutines(info, cMethods, callMethods, NULL, NULL);
R_useDynamicSymbols(info, FALSE);
}
