The short answer is that you need to use the window() command with ts objects.
The (ever so slightly) longer answer is that no one really likes ts
objects and that's why a proliferation of contributed packages exist
to deal with their "idiosyncracies". The most popular for finance are
zoo and xts and I heartily recommend you start using those for your
analysis if at all possible. If you use those, you can use simple
commands like x[1:250] to get the first 250 elements or you can subset
by time for xts which is very nice.
