Dear R People:
When I have a time series, I can get the frequency of the series via tsp(x)[3].
Is there a similar function for xts and zoo objects, please?
Thanks,
Erin

Note that the preferred way of doing this with ts series is to use the
frequency() function rather than using tsp. That function also works
for zoo objects.

Here is something that I just ran into. I have a business day series,
spc, which I obtained using get.hist.quote.
When I tried frequency(spc), I got 1.
str(spc)
‘zoo’ series from 1998-01-02 to 2010-04-09

1 is the correct answer. The difference between successive time
values, deltat, is 1 or a multiple of 1 and frequency is the
reciprocal of deltat.
