[R] non-nested models testing

[Bruno Giordano]

Hi,
I'm trying to figure out some stastistics for non-nested models testing.
Among them:
[1] Vuong statistic (Vuong, 1989)
[2] Distribution-free test by Clarke (2003).
Did someone wrote a piece of [R] code to compute any of them?
Many thanks,
    Bruno
