distantia (version 2.0.2)

distantia_ls: Lock-Step Dissimilarity Analysis of Time Series Lists

Description

Minimalistic but slightly faster version of distantia() to compute lock-step dissimilarity scores.

Usage

distantia_ls(tsl = NULL, distance = "euclidean")

Value

data frame:

• x: time series name.

• y: time series name.

• distance: name of the distance metric.

• psi: psi dissimilarity of the sequences x and y.

Arguments

tsl

(required, time series list) list of zoo time series. Default: NULL

distance

(optional, character vector) name or abbreviation of the distance method. Valid values are in the columns "names" and "abbreviation" of the dataset distances. Default: "euclidean".
