Description:
 def roll(self, shifts=None, roll_coords=None, **shifts_kwargs):
 """Roll this array by an offset along one or more dimensions. Unlike shift, roll may rotate all variables, including coordinates if specified. The direction of rotation is consistent with :py:func:`numpy.roll`. Parameters roll_coords : bool Indicates whether to roll the coordinates by the offset The current default of roll_coords (None, equivalent to True) is deprecated and will change to False in a future version. Explicitly pass roll_coords to silence the warning. **shifts : keyword arguments of the form {dim: offset} Integer offset to rotate each of the given dimensions. Positive offsets roll to the right; negative offsets roll to the left. Returns ------- rolled : DataArray DataArray with the same attributes but rolled data and coordinates. See also -------- shift Examples -------- <xarray.DataArray (x: 3)> array([7, 5, 6]) Coordinates: * x (x) int64 2 0 1 """
