distances Different distances between two given vectors Description These functions are used for calculating different distances between two given vectors. Thus, L1.dist calculates the L1 distance, cosin.dist calculates the cosine distance, euclidian.dist computes the Euclidian distance, and rank.cor.dist computes the rank correlation distance. The vectors have to have same length. When using r...
