internal functions in R

[Alex C]

Hi,
I'm trying to use an already existing function in R and add a few lines at the end to display more stats, when I try that I get an error message because there is an internal function in the program that won't work if I'm not using the original program. Is there any way to get around this or to see details about internal functions?

I'm using the luca package and function in R, there is the "get.lambda" internal function that gives me an error message if I try to use it outside of the luca command. I am not familiar with internal functions R so I wonder if there is a way to use internal functions if someone wants to slightly alter an existing function.

I found the answer, using getAnywhere("_function_name_") works
