View source: R/windowing.R

Description

The repr_windowing computes representations from windows of a vector.

Usage

1
repr_windowing(x, win_size, func = NULL, args = NULL)

Arguments

x

the numeric vector (time series)

win_size

the length of the window

func

the function for representation computation. For example repr_feaclip or repr_trend.

args

the list of additional arguments to the func (representation computation function). The args list must be named.

Details

This function applies specified representation method (function) to every non-overlapping window (subsequence, piece) of a time series.

Value

the numeric vector
