Ah, yes. Much better -- that is what match.call() is for.
As always, thanks for the insight,

Hi, every R user,
I wanna output names of objects, I googled codes from website, but it
was not what I wanted.
the codes are as following:
f <- function (...)
{
unevaluatedArgs <- substitute(...())
evaluatedArgs <- list(...)
stopifnot(length(unevaluatedArgs) == length(evaluatedArgs))
