shift: Function to shift the elements of a vector.

Description

The function makes use of the function 'fitler' to delay or advance a signal by k points.

Usage

shift(x, delta = 1, circular = TRUE)

Arguments

x

A numeric vector

delta

A single element numeric vector. Defines the number of points by which the signal should be shifted.

circular

Logical. If T, the signal is wrapped around itself so that if delta = 1, x[n] becomes x[1]. Otherwise, if delta is positive, the same number of zeros are prepended to the signal

Value

• The signal shifted by a certain number of points. ...

Details

The function makes use of the function 'filter' for linear filtering to carry out the shifting.
