Produces an unsorted central moment object from a sorted object of class "moment".
Unsorted moments are those with exponents not in numeric order, e.g., m312.
tounsorted(moment,sorted.moment)
unsorted moment to obtain moment is in vector form, eg, c(3,1,2)
sorted moment to use in obtaining unsorted moment
A object of class 'moment', which is a list with three components:
the input moment vector
a matrix containing the representation in terms of upper-triangular matrices
the coefficients corresponding to the rows of the representation
The unsorted moment is obtained by resorting the rows and columns of the sorted moment sucessively.
