The series function imports all tables that can be saved in
X-13ARIMA-SEATS.
series(x, series, reeval = TRUE, verbose = TRUE)depending on the table, either an object of class "ts" or
"data.frame".
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).
