Data Transformation: Local Centering and Scaling

Scaling and/or centering by variable and time series. Local scaling helps dynamic time warping focus entirely on shape comparisons.

Usage

f_scale_local(x = NULL, center = TRUE, scale = TRUE, ...)

Arguments

x

(required, zoo object) Zoo time series object to transform.

center

(optional, logical or numeric vector) Triggers centering if TRUE. Default: TRUE

scale

(optional, logical or numeric vector) Triggers scaling if TRUE. Default: TRUE

...

(optional, additional arguments) Ignored in this function.

Value

zoo object
