[Rd] Finding inter-function dependencies within a package

[Keith Jewell]

Hi,

I'd like to know which functions in a package call one specific function.
I think I've seen a tool for identifying such dependencies, but now I can't 
find it :-(
Searches of help and R site search for keywords like function, call, tree, 
depend haven't helped :-(

Can anyone point me in the right direction?

Thanks in advance,

Keith Jewell
