I should note that I realise this function is pretty trivial to write
(see below), I just want to avoid reinventing the wheel.
recyclable <- function(...) {
lengths <- vapply(list(...), length, 1)
all(max(lengths) %% lengths == 0)
}

Hi all,
Is there a function to determine whether a set of vectors is cleanly
recyclable? i.e. is there a common function for detecting the
error/warnings that underlie the following two function calls?
> 1:3 + 1:2
[1] 2 4 4
Warning message:
In 1:3 + 1:2 :
longer object length is not a multiple
2 matches
