Lifecycle: stable R-CMD-check CRAN status Test coverage BuyMeACoffee

About

Please read my article for the full details of this project (Open Access):

Vargas Sepulveda, Mauricio. 2025. ‘Kendallknight: An R package for efficient implementation of Kendall’s correlation coefficient computation’. PLOS ONE 20 (6): e0326090. https://doi.org/10.1371/journal.pone.0326090.

This package implements a different algorithm from the one implemented in base R, and it reduces the complexity of the Kendall’s correlation coefficient from O(n^2) to O(n log n) resulting in a runtime of nano seconds or minutes instead of minutes or hours. This package is written in C++ and uses cpp11 to export the functions to R. See the vignette for the mathematical details.

If this software is useful to you, please consider donating on Buy Me A Coffee. All donations will be used to continue improving kendallknight.
