Abstract: group_twoway groups observations by the connected components of the parent and child variables. For instance, given a list of family relationships between people, this grouping will connect any two individuals for whom there is a "family path" connecting them (cousin, of a cousin, of a cousin, etc) even if there are no direct family relationships between them. This can be useful when classifications (sectorial, regional) change over time and one wants to create a constant classification over the period.
