Overview

About

Maintained by Toshihiro IguchiCRAN page ↗GitHub ↗Issues ↗

Provides a single unified interface for computing a wide variety of classical and modern correlation and association measures. Continuous methods include classical correlations (Pearson, Spearman, Kendall), modern dependence measures (distance correlation, maximal information coefficient, Hilbert-Schmidt independence criterion, Chatterjee's xi, Hoeffding's D, mutual information), robust correlations (biweight midcorrelation, percentage bend, Winsorized), ordinal correlations (polychoric, tetrachoric), partial and semi-partial correlations, and nonparametric measures (ball correlation, Bergsma-Dassios tau*). Categorical association measures (Cramer's V, phi coefficient, Goodman-Kruskal gamma, Somers' D, contingency coefficient, Tschuprow's T) are available via moderncor_cat().

Changes in 0.2.0

New Features

Added robust correlation methods: biweight midcorrelation, percentage bend correlation (WRS2), and Winsorized correlation (WRS2).
Added ordinal correlation methods: polychoric and tetrachoric correlation (psych).
Added partial correlation methods: partial correlation and semi-partial correlation (ppcor), controlled via the new z parameter.
Added nonparametric methods: ball correlation (Ball) and Bergsma-Dassios tau* (TauStar).
Added moderncor_cat() for categorical association measures: Cramer's V, phi coefficient, Goodman-Kruskal gamma, Somers' D, contingency coefficient, and Tschuprow's T (all via DescTools).

Show all changes in 0.2.0Hide the rest of the changes in 0.2.0

Added available_methods_cat() to list all supported categorical methods.

Changes

Removed dependency on WGCNA (Bioconductor). Biweight midcorrelation is now computed using a built-in implementation of the standard formula (Wilcox 2012), eliminating the need for Additional_repositories.
Version bumped to 0.2.0 to reflect the substantial addition of Phase 2 methods.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("moderncor", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("ToshihiroIguchi/moderncor")

Development version from ToshihiroIguchi/moderncor. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-moderncor

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-moderncor

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-moderncor

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
