Hi,
Is there a function taking a function as an argument, which returns all the
functions it calls, and all the the functions those functions call, and so
on? I could use Rprof, but that would involve executing the function,
which may miss some branches of code. I'd really like a function which
looks at the source code to work out all the functions that could possibly
be called. When I develop a function and release to production environment
(or to some library) then I may need to release other functions I've
developed which that function calls. As soon as the function call stack
goes outside .GlobalEnv (for example into base) then the search can stop as
I'm only interested in functions in .GlobalEnv (my own functions). Also
useful would be the reverse function i.e. find all functions which could
possibly call the function. This could be used to find functions which are
never called and could be considered for deletion.
Thanks,
Matthew
