In ConsRank: Compute the Median Ranking(s) According to the Kemeny's Axiomatic Approach

Plot rankings on a permutation polytope of 3 o 4 objects containing all possible ties

Description

Plot rankings a permutation polytope that is the geometrical space of preference rankings. The plot is available for 3 or for 4 objects

Usage

polyplot(X = NULL, L = NULL, Wk = NULL, nobj = 3)

Arguments

X	the sample of rankings. Most of the time it is returned by tabulaterows
L	labels of the objects
Wk	frequency associated to each ranking
nobj	number of objects. It must be either 3 or 4

Details

polyplot() plots the universe of 3 objecys. polyplot(nobj=4) plots the universe of 4 objecys.

Value

the permutation polytope
