[R] checking frequency in xts and zoo objects

[Erin Hodgess]

Thank you!

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
  Data: num [1:3086, 1] 975 977 967 964 956 ...
 - attr(*, "dimnames")=List of 2
  ..$ : NULL
  ..$ : chr "Close"
  Index: Class 'Date'  num [1:3086] 10228 10231 10232 10233 10234 ...
> frequency(spc)
[1] 1
>

Am I doing something wrong(high probability) or maybe frequency does
not work the same with business day data, please?

Thanks,
Erin
