Thanks Jim -- I had considered this approach; is there any way to hide
such arguments from users?

Make the flag an attribute of the function? Unless the user looks at
the attributes, it will be invisible.
(Not sure this does what you want, but maybe it's useful.)

Don't export the recursive function, just a non-recursive function that
calls it.

Hi Ben,
I played around with your solution for a while and if the first argument
to the function changes with each recursive call, you may be able to
Given a function that calls itself, what's the best way to detect the
entry point? The best I came up with is:
IsEntryPoint - function(){
par - sys.call(-1L)[[1]]
grandpar - sys.call(-2L)[[1]]
!identical(par, grandpar)
}
but this won't work for functions that don't directly
