shiftPositions
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 noninteger 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.
