Sven, could you give an idea of what you expected here? Seems to me that while discarding a series containing NAs would leave you with a time series dataset, discarding observations is bound to destroy the time series property (unless the NAs were just at the start and/or end of the data).

OK, on a little simulation I see that case is not being handled correctly -- i.e. time series structure not preserved on making the restriction permanent. Fix should be forthcoming before long.
