shift

Function to shift the elements of a vector.

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

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

`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

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

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