colorplot               colored dendrogram plot of a labclust object
is.aggvec               checks wheather or not one vector is
                        agglomeration of the another
labclust                labclust is an object
labeltodendro           converts series of labels to a labclust object
labeltotable            counts the number of labels appeared in a label
                        matrix and finds the most frequent labelling
                        and agglomeration and divisions of it.
plot.labclust           dendrogram plot of a labclust object
relabel                 relabels a vector, insisting that the labels
                        appear in increasing order
relabel.matrix          relabels a matrix label insisting that the
                        labels of each row appear in increasing order
selectlabels            it is useful to sort labels in agglomerative
                        order
tabletodendro           converts a label matrix and a frequency vector
                        to a labclust object
