Just be aware that ccf will standardize the series at the beginning of the exercise. so results won’t match those done with cor – on lagged data. I recognize your example was set to lag 0, so this isn’t an issue using this code exactly as presented. thanks!

Can you please add it?

My data have 24 hours periodicity but my periodogram give me these result how to interpret that? my data are sampled every 15min. Sample size: 36411

the result: freq spec 2 5.486968e-05 134.42945 1 2.743484e-05 69.86439

time= 1/top2$f
time
1 18225 36450
