RankGraph (Combinatorica Package Symbol)

RankGraph[g, l] partitions the vertices into classes based on the shortest geodesic distance to a member of list l.

RankRGF (Combinatorica Package Symbol)

RankRGF[f] returns the rank of a restricted growth function (RGF) f in the lexicographic order of all RGFs.

RealizeDegreeSequence (Combinatorica Package Symbol)

RealizeDegreeSequence[s] constructs a semirandom graph with degree sequence s.

RegularQ (Combinatorica Package Symbol)

RegularQ[g] yields True if g is a regular graph.
