yes, thats a pretty good fit (and no, I'm not asking about internal C
code), thanks.

So now that I have ways to extract machine-readable info about an R
function, how can I map all functions in an R package without having
prior knowledge about the package's content?

In pseudo-code, something like (apply 'formals (pkg-functions "PKG")).

If I'm lucky, there exist another simple function for that too
... thanks again for any hints.
