mars.dataframe.DataFrame.tshift

DataFrame.tshift(periods: int = 1, freq=None, axis=0)

Shift the time index, using the index’s frequency if available.

Parameters

• periods (int) – Number of periods to move, can be positive or negative.

• freq (DateOffset, timedelta, or str, default None) – Increment to use from the tseries module or time rule expressed as a string (e.g. ‘EOM’).

• axis ({0 or ‘index’, 1 or ‘columns’, None}, default 0) – Corresponds to the axis that contains the Index.

Returns

shifted

Return type

Series/DataFrame

Notes

If freq is not specified then tries to use the freq or inferred_freq attributes of the index. If neither of those attributes exist, a ValueError is thrown
