Yes, I do.

Assuming that your next question will be "How do you do this?" I will
answer that one too.  You begin by reading the manual "Writing R
Extensions".  If, as you indicate, you don't know much about
programming in C that manual will be a tough read, but that is the
nature of the beast.  You want to do something complicated and you
will need to learn quite a bit to be able to do it.
