R which function runs another function

Question

I have code like this:

f.internal <- function(){
  print("f.internal was called by ...")
}

f.external <- function(){
  f.internal()
}

How to check in R, which of the two functions runs the other function?

Write a helper named getCaller(), which uses stop() within a tryCatch to generate a traceback call stack. Using that it can identify the last few calling functions.

Then have f.internal() call the helper to produce the desired output.
