	Name	Description
	StackR, C(DataFrameR, C, Boolean)	Transforms a data frame so that the column index is nested into the row index.
	StackR, C1, C2(DataFrameR, ValueTupleC1, C2, Boolean)	Transforms a data frame so that the second level of a two-level column index is nested into the row index.
	StackR1, R2, C(DataFrameValueTupleR1, R2, C, Boolean)	Transforms a data frame so that the column index is nested into the row index.
	StackR(DataFrameR, String, IEnumerableString, IEnumerableString, String, String)	Returns a data frame containing all values in the data frame as row-column-value pairs.
