[R] Vogelsang test? RATS? Time series analysis.

Has anybody implemented the Vogelsang test from Vogelsang's 1998
Econometrica paper? Or the tests by Fomby and Vogelsang from their 2002

I have been looking for trends in many time series (1000's) with unknown
autocorrelation. In brief, I have fit AR models  and classified them as
stochastic or deterministic with augmented Dickey-Fuller tests. A colleague
has suggested that we use a "new and more elegant test" that is robust to
the nature of serial correlation in the residuals and pointed me the RATS
program in general and Fomby and Vogelsang test in particular.

Any leads appreciated, Andy
