ref_line <- match.arg(ref_line)
the first entry of the default values in the function argument is always used used as the default when a user does not specify anything. There is no need for the complications of the if statement or the use of several.ok = FALSE because that is the default behavior of match.arg().
See the below example of calling optim in R where they also use match.arg()
