Overview

About

Maintained by Wenbo LyuCRAN page ↗GitHub ↗Website ↗Issues ↗

Implements information-theoretic measures to explore variable interactions, including KSG mutual information estimation for continuous variables from Kraskov et al. (2004) doi:10.1103/PhysRevE.69.066138, knockoff conditional mutual information described in Zhang & Chen (2025) doi:10.1126/sciadv.adu6464, synergistic-unique-redundant decomposition introduced by Martinez-Sanchez et al. (2024) doi:10.1038/s41467-024-53373-4, and information imbalance gain following Del Tatto et al. (2024) doi:10.1073/pnas.2317256121, allowing detection of complex and diverse relationships among variables.

Changes in 0.3

new

Provide R-level API and vignette for infomation imbalance and imbalance gain (#91).

enhancements

discretize() now safely falls back to factor encoding (NA as 0) for edge cases (#98).

breaking changes

Euclidean/Manhattan distances now automatically compensate for dimensions skipped due to NA/NaN, aligned with base R dist() (#96).
Remove leading lag-induced NA values in surd time-series implementation (#83).

From NEWS.md in the release

Install

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

install.packages("infoxtr", 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("stscl/infoxtr")

Development version from stscl/infoxtr. 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-infoxtr

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-infoxtr

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-infoxtr

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.
