- Note
- Column operations return a DataMap[K] as a subtype of DataFrame.
- You can drop the group columns but altering or replacing a group column results in an IllegalOperation exception
(for methods which return the type
DataMap[K]). - Note that index changing operations return a DataFrame since the mapping is no longer applicable to the resulting DataFrame.
