[R] Debugging functions defined (locally) inside another functions

To be precise, in the case I am looking this time f is not a function, but

f <- ggplot2::ggproto(...)

So debug(f) produces
Error in debug(f) : argument must be a function

Tema: [R] Debugging functions defined (locally) inside another functions

Hi all, I am trying to debug an error of a function g defined and used inside another function f of a package.
So I have

f <- function(whatever){
   g <- function(whatever2){

If I wanted to debug some thing directly inside f I would do debug(f). But this does not go inside g code. On the other hand, debug(g) does not work as g is not a defined function in the namespace of the package.

Is there some way to debug errors inside g?

Thank you in advance.

All the best,
