[Rd] C code in packages with complex arguments/returned value

Hi
one of my packages has a severe bottleneck at a particular function
and I
suspect that replacing the R code with C code would speed it up.
The function takes complex arguments and returns a complex value.
I would like to follow Best Practice here. None of the C code in my
packages includes the ability to handle complex numbers (this is done
by R).
Does anyone know of a package that includes C code which manipulates
and returns complex arguments that I could take a look at?
Yes, there is src/main/complex.c, but I would like to see how complex
arithmetic is
done in a package (or how it should be done).
