final {seasonal}

Time Series of a Seasonal Adjustment Model

Description

Functions to extract the main time series from a "seas" object. For universal import of X-13ARIMA-SEATS tables, use the series() function.

Usage

final(object)

original(object)

trend(object)

irregular(object)

## S3 method for class 'seas'
residuals(object, ...)

Arguments

object

an object of class "seas".

...

not used. For compatibility with the generic.

Details

These functions support R default NA handling. If na.action = na.exclude is specified in the call to seas, the time series will also contain NAs.

Value

returns a "ts" object, depending on the function.

# NA handling
AirPassengersNA <- window(AirPassengers, end = 1962, extend = TRUE)
final(seas(AirPassengersNA, na.action = na.omit))    # no NA in final series
final(seas(AirPassengersNA, na.action = na.exclude)) # NA in final series
final(seas(AirPassengersNA, na.action = na.x13))     # NA filled by x13
# final(seas(AirPassengersNA, na.action = na.fail))    # fails
