Co-Operation: Fast Covariance, Correlation, and Cosine Similarity Operations R package coop version 0.6-3 Fast implementations of the co-operations: covariance, correlation, and cosine similarity. The implementations are fast and memory-efficient and their use is resolved automatically based on the input data, handled by R's S3 methods. Full descriptions of the algorithms and benchmarks are available in the package vignettes.
