I'm not sure if it's easily doable with a ts class, but the rollapply
function in the zoo package will do this easily. (Also, I find zoo to
be a much more natural time-series workflow than ts so it might make
the rest of your life easier as well)

Hi,
I want to apply a function (in my case SDF; package “sapa”) repeatedly over
discrete sections of a daily time series object by sliding a time window of
constant length (e.g. 10 consecutive years or 1825 days) over the entire ts at
increments of 1 time unit (e.g. 1 year or 365 days). So for
7 matches
