labels

a  ranking, or a n by m data matrix in which there are n judges ranking m objects

label

labs = 1 displays the names of the objects if there is argument &quot;label&quot;, otherwise displays the permutation of first m integer. labs = 2 is to be used only if the argument &quot;label&quot; is not defined. In such a case it displays the permutation of the first m letters

labs

Given a ranking (or a matrix of rank data), transforms it into an ordering (or a ordering matrix)

Compute the median ranking according to the Kemeny's axiomatic approach.
Rankings can or cannot contain ties, rankings can be both complete or incomplete.
The package contains both branch-and-bound algorithms and heuristic solutions recently proposed.
The package also provide some useful utilities for deal with preference rankings.
