Retrieves the raw, seasonal, trend, remainder, or time components from an stl2 object. The methods `seasonal.stl`

, ... also exist as a convenience for extracting components from R's `stl()`

.

`x, object` |
object of class |

`fcnum` |
number of post-trend smoothing frequency component. |

`...` |

Returns a vector of either the `getraw`

time series, the `seasonal`

, `trend`

, or `remainder`

components, or the `time`

values of the time series. If `time`

s are requested but were not supplied in the initial `stl2`

call, the `1:n`

vector is returned, where `n`

is the number of data points. The `fitted`

method returns the sum of the seasonal and trend.

The `fitted`

and `predict`

methods are equivalent. For objects of class `"stl2"`

, these functions return the sum of all components but the remainder, including post-trend smoothing components. Note also that the `trend`

method for objects of class `"stl2"`

only returns the trend component from the STL iterations, even when post-trend smoothing is done.
