[R] analysis of function dependencies / namespacing

[oehl_list@gmx.de]

I am going to document a 10.000 lines of R code project.

Before reinventing the wheel, has anyone written a function that analyzes
dependencies between R functions? 

I am thinking of output like 

caller1  calee1
caller1  calee2
caller1  :
caller2  calee7
:

and I would like to restrict caller and callee to certain positions in the
search path.
My guess is, that a quick and dirty solution is easy, but I have no idea how
to filter out calls to locally defined functions. 

Furthermore I heard rumors about newnamespacing features. Is there already
information on that?

Thanks for any help
Best
