Shift

Description

Class to shift a dataset.

Format

R6Class object.

Details

Transform autocorrelations to intervariables correlations

Value

Object of R6Class

Methods

new(lag,method,ref,)

This method is used to create object of this class with Shift

transform(X)

Method to shift a dataset

inverse(Xs)

Method to inverse the shift of a dataset

Public fields

lag

[integer] max lag for autocorrelations

Active bindings

method

[character] If inverse is by row or column.

ref

[integer] reference column/row to inverse shift.

Methods

Public methods

• Shift$new()

• Shift$transform()

• Shift$inverse()

• Shift$clone()

Method new()

Create a new Shift object.

Usage

Shift$new(lag, method = "row", ref = 1)

Arguments

lag

[integer] max lag for autocorrelations

method

[character] If "row" inverse by row, else by column

ref

[integer] starting point for inverse transform

Returns

A new 'Shift' object.

Method transform()

Shift the data

Usage

Shift$transform(X)

Arguments

X

[matrix: n_samples * n_features] Data to shift

Returns

[matrix] Matrix shifted

Method inverse()

Inverse the shift of the data

Usage

Shift$inverse(Xs)

Arguments

Xs

[matrix] Data Shifted

Returns

[matrix] Matrix un shifted

Method clone()

The objects of this class are cloneable with this method.

Usage

Shift$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

X = base::t(matrix( 1:20 , nrow = 2 , ncol = 10 ))

sh = Shift$new(1)
Xs = sh$transform(X)
Xi = sh$inverse(Xs)
