My series was regularly spaced, it simply contained missing values. I don't
see why the new values were added.

Besides, my previous email showed exactly how to convert a zoo object with
missing values into a ts object with missing values and a frequency other
than 1, so I'm not sure what you mean:

> z = zoo(x, order.by=t)
> t = as.ts(z)
> frequency(t)
[1] 1
> length(t)
[1] 92064
> tt = ts(t, frequency=24)
> frequency(tt)
[1] 24
> length(tt)
[1] 92064
