[Rd] rep(): Expecting an argument-is-missing error, but ...

[Peter Langfelder]

I think it's a bit of a quirk of rep:

> rep("x")
> [1] "x"

Help of 'rep' does state this:

The default behaviour is as if the call was

       rep(x, times = 1, length.out = NA, each = 1)

So it seems to even be documented.
