| polyplot {ConsRank} | R Documentation |
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
