Examples

## periodic ts object => peridic acf
autocorrelations(pcts(AirPassengers), maxlag = 10)

## for "ts" or "numeric" objects the default is non-periodic acf
autocorrelations(AirPassengers, maxlag = 10) 
autocorrelations(as.numeric(AirPassengers))
## argument 'nseasons' forces periodic acf
autocorrelations(AirPassengers, maxlag = 10, nseasons = 12)
autocorrelations(as.numeric(AirPassengers), maxlag = 10, nseasons = 12)
