This still does not give me the desired behavior:
> z = zoo(x, order.by=t, frequency=24)
> t = as.ts(z)
... inserts 23 NA values between every actual value. This is not correct;
the original data has a frequency of 24 and doesn't need one forced upon it
during coercion.
> z = zoo(x, order.by=t)
> t = as.ts(z)
... obviously doesn't give me a ts with frequency 24.
Keep in mind that I'm trying to get a ts with frequency 24 so I can feed it
to stl. I haven't yet found a sequence of operations that lets me do this.
Any ideas?
