Computes the leave-one-out one-nearest-neighbor cross-validation of an arbitrary distance matrix.
Integer vector with the labels of the true cluster solution. Each element of the vector specifies the cluster 'id' that the element belongs to.
Computes the proportion of succesful clusters that the given distance matrix produces using leave-one-out one-nearest-neighbor cross-validation. Distance ties are solved by majority vote. A tie while voting produces a warning and is solved by selecting a candidate cluster at random.
The computed proportion.
