I am trying to write a function that takes a few objects as input.

test <- function(directory, num = 1:100) {
> }


the argument, "num", has the default value. But when the function is
called, it can take an array as well,

test("directory", c(1, 2, 3))


I can parse the both arguments by converting them into string, but I am
wondering if there is a better (more efficient) way to achieve this.
Perhaps, using built-in R functions can help, I suppose?

Does anyone have any idea for the function taking more than one kind of
argument?
