<dd>a vector or <code>timeDate</code> object.
Missing values (<code>NA</code>s) are allowed.</dd><dt>k</dt>
<dd>the number of positions the input series is to shift for the new series.<ul>
<li>If <code>k</code> is a positive value, the resulting series is shifted forwards in time.</li>
<li>If <code>k</code> is a negative value, the resulting series is shifted backwards in time.</li>
</ul>If <code>k</code> is a non-integer value, it is rounded to the nearest integer before the shift is applied.</dd></dl>
