convertRank converts a rank from its ranking representation to its ordering representation, and vice-versa. The function does not work with partial ranking. The transformation to convert a rank from ordering to ranking representation is the same that from ranking to ordering representation, there is no need to precise the representation of rank x.
convertRank(x)a rank (vector) in its ordering representation if its ranking representation has been given in input of convertRank, and vice-versa.
a rank (vector) datum either in its ranking or ordering representation.

The ranking representation r=(r_1,...,r_m) contains the ranks assigned to the objects, and means that the ith object is in r_ith position.
The ordering representation o=(o_1,...,o_m) means that object o_i is in the ith position.
Let us consider the following example to illustrate both notations: a judge, which has to rank three holidays destinations according to its preferences, O1 = Countryside, O2 =Mountain and O3 = Sea, ranks first Sea, second Countryside, and last Mountain. The ordering result of the judge is o = (3, 1, 2) whereas the ranking result is r = (2, 3, 1).
x <- c(2, 3, 1, 4, 5)
convertRank(x)
