shiftPositions: Shift a Positions Object

In splusTimeDate: Times and Dates from S-PLUS

Shift a Positions Object

Description

Returns a positions object similar to the input but shifted in time.

Usage

shiftPositions(x, k=1)

Arguments

x	a vector or timeDate object. Missing values (NAs) are allowed.
k	the number of positions the input series is to shift for the new series. If k is a positive value, the resulting series is shifted forwards in time. If k is a negative value, the resulting series is shifted backwards in time. If k is a non-integer value, it is rounded to the nearest integer before the shift is applied.

Value

returns a vector or timeDate object with the positions shifted by k steps.
