critFunKmeans           Function that computes criterion function used
                        in k-means like one-mode blockmodeling. If
                        'clu' is a list, the method for
                        linked/multilevel networks is applied
kmBlockC                Function that performs k-means like one-mode
                        blockmodeling. If 'clu' is a list, the method
                        for linked/multilevel networks is applied
kmBlockORPC             A function for optimizing multiple random
                        partitions using k-means one-mode and linked
                        blockmodeling. Calls 'kmBlockC' for optimizing
                        individual random partitions.
