Re: [R] Continuation-parsing / trampoline / infinite recursion problem

Yes, I am aware of this situation and I agree that it is better to force f. I was simply trying to figure out why it was necessary in this particular program where the only repeated assignment anywhere in the code is in trampoline, in a scope none of the thunks can see. What ever my problem

Re: [R] Continuation-parsing / trampoline / infinite recursion problem

  Well, they stay at 3 when I call cat (except for the final step going down in they recursion where `identity` is called, where they are 4). They do that both when I evaluate ... in the `make_thunk` function and when I don’t. But then, when I call `cat` it also worked before. I cannot keep

Rejecting a null of "inequality" is the standard setup for equivalence testing in medical contexts. Search on "equivalence testing in R" and you will find what you need. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into
