Hi,
I'm trying to make a ts object that has both NA values and a frequency other
than 1 (so I can use stl). I've tried all permutations I can think of, but
cannot get the desired (expected?) results.
The values live in x and the corresponding semi-regular time stamps are in
t:
> library('zoo')
> z = zoo(x, order.by=t, frequency=24)
> zzr = as.zooreg(z, start=0)
> zr = zooreg(x, order.by=t, start=0, frequency=24)
> zrz = as.zoo(zr)
The objects z, zr, and zzr all have frequency 24, as desired, and plot
correctly. Object zrz plots correctly but has frequency 1. Now I try to make
it a ts object:
> zrt = ts(zzr)
... omits the missing values.
> zrt = ts(zzr, frequency=24)
... omits the missing values and changes the timestamps.
> plot(ts(zr))
... omits the missing values.
> zrt = ts(zr, frequency=24)
... omits the missing values and changes the timestamps.
> zrt = as.ts(zr)
... inserts 23 NA values between each legitimate value.
> zrt = as.ts(zr, frequency=24)
... inserts 23 NA values between each legitimate value.
> zrzt = ts(zrz)
... omits the missing values.
> zrzt = ts(zrz, frequency=24)
... omits the missing values and changes the timestamps.
Could someone tell me how to get the desired ts object?
Sincerely,
