Functions to extract the main time series from a
"seas" object. For
universal import of X-13ARIMA-SEATS tables, use the
final(object) original(object) trend(object) irregular(object) ## S3 method for class 'seas' residuals(object, ...)
an object of class
not used. For compatibility with the generic.
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.
"ts" object, depending on the function.
