What's wrong with that? S looks silly to me: you only need the second
component for seasonal series, and 1:10 is not seasonal.
In general, I am not trying to clone S, most notably as S-PLUS uses class
rts not ts, so very little code exists that uses S's class ts. Surely the
point of R is not _better_? There are lots of detail improvements,
with more to come.

I have not changed window.ts. I'll take a look.
