# pandas.DataFrame.combineAdd

`DataFrame.``combineAdd`(other)

  DEPRECATED. Use `DataFrame.add(other, fill_value=0.)` instead.

  Add two DataFrame objects and do not propagate NaN values, so if for a (column, time) one frame is missing a value, it will default to the other frame’s value (which might be NaN as well)

  Parameters: | other : DataFrame
  Returns: | DataFrame
