Import X-13ARIMA-SEATS Output Tables

With the exception of the composite spec, the series function imports all tables that can be saved in X-13ARIMA-SEATS.

series(x, series, reeval = TRUE, verbose = TRUE)

an object of class "seas".


character vector, short or long names of an X-13ARIMA-SEATS table. If a long name is specified, it needs to be combined with the spec name and separated by a dot (it is not unique, otherwise. See list below.). More than one series can be specified (see examples).


logical, if TRUE, the model is re-evaluated with the corresponding specs enabled.


logical, if TRUE, a message is returned if a spec is added during reevaluation.


If the save argument is not specified in the model call, series re-evaluates the call with the corresponding specs enabled (also returning a message). Note that re-evaluation doubles the overall computational time. If you want to accelerate the procedure, you have to be explicit about the output in the model call (see examples).

### Some X-13ARIMA-SEATS functions can be replicated in R:

# X-13ARIMA-SEATS spectrum
plot(series(m, "spectrum.specorig")[,-1], t = "l")
# R equivalent: spectrum from stats
spectrum(diff(log(AirPassengers)), method = "ar")

# X-13ARIMA-SEATS pacf
x13.pacf <- series(m, "identify.pacf")
plot(x13.pacf[,1], t = "h")
# R equivalent: pacf from stats
pacf(AirPassengers, lag.max = 35)
# }
