          Parameters
          ----------
          datetime : boolean, default False
              If True, convert to date where possible.
          numeric : boolean, default False
              If True, attempt to convert to numbers (including strings), with
              unconvertible values becoming NaN.
          timedelta : boolean, default False
              If True, convert to timedelta where possible.
          coerce : boolean, default False
              If True, force conversion with unconvertible values converted to
              nulls (NaN or NaT)
          copy : boolean, default True
              If True, return a copy even if no copy is necessary (e.g. no
              conversion was done). Note: This is meant for internal use, and
              should not be confused with inplace.
  
          Returns
          -------
          converted : same as input object
