Overview

About

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

Infer causation from observational data through pattern causality analysis (PC), with original algorithm for time series data from Stavroglou et al. (2020) doi:10.1073/pnas.1918269117, as well as methodological extensions for spatial cross-sectional data introduced by Zhang & Wang (2025) doi:10.1080/13658816.2025.2581207, together with a systematic description proposed in Lyu et al. (2026) doi:10.1016/j.compenvurbsys.2026.102435.

Changes in 0.3

new

Provide dmi generic for *delayed mutual information* method (#77).

enhancements

Clarify output indexing and boundary handling in fnn generic (#69).

breaking changes

Reverse argument order for variable indices to (source, target) (#85).
Impose geometric constraint k >= E+1 in ops generic (#81).
Euclidean/Manhattan distances now automatically compensate for dimensions skipped due to NA/NaN, aligned with base R dist() function (#79).

bug fixes

Fix incorrect prediction horizon parameter in the time series pattern causality implementation (#80).

From NEWS.md in the release

Install

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

install.packages("pc", 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/pc")

Development version from stscl/pc. 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-pc

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-pc

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-pc

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.
