Import Time Series from X-13 Data Files

Description

Utility function to read time series from X-13 data files. A call to import.ts is constructed and included in the output of import.spc().

Usage

import.ts(
  file,
  format = "datevalue",
  start = NULL,
  frequency = NULL,
  name = NULL
)

Arguments

`file`	character, name of the X-13 file which the data are to be read from
`format`	a valid X-13 file format as described in 7.15 of the X-13 manual: `"datevalue"`, `"datevaluecomma"`, `"free"`, `"freecomma"`, `"x13save"`, `"tramo"` or an X-11 or Fortran format.
`start`	vector of length 2, time of the first observation (only for formats `"free"` and `"freecomma"` and the Fortran formats.)
`frequency`	the number of observations per unit of time (only for formats `"free"`, `"freecomma"` and the X-11 or Fortran formats.)
`name`	(X-11 formats only) name of the series, to select from a file with multiple time series. Omit if you want to read all time series from an X-11 format file.

Value

an object of class ts or mts

Examples

tdir <- tempdir()
seas(x = AirPassengers, dir = tdir)
import.ts(file.path(tdir, "iofile.dta"))
