Performs a series of offline and/or online change-point detection algorithms for 1) univariate mean: doi:10.1214/20-EJS1710, arXiv:2006.03283; 2) univariate polynomials: doi:10.1214/21-EJS1963; 3) univariate and multivariate nonparametric settings: doi:10.1214/21-EJS1809, doi:10.1109/TIT.2021.3130330; 4) high-dimensional covariances: doi:10.3150/20-BEJ1249; 5) high-dimensional networks with and without missing values: doi:10.1214/20-AOS1953, arXiv:2101.05477, arXiv:2110.06450; 6) high-dimensional linear regression models: arXiv:2010.10410, arXiv:2207.12453; 7) high-dimensional vector autoregressive models: arXiv:1909.06359; 8) high-dimensional self exciting point processes: arXiv:2006.03572; 9) dependent dynamic nonparametric random dot product graphs: arXiv:1911.07494; 10) univariate mean against adversarial attacks: arXiv:2105.10417.

Install

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

install.packages("changepoints", 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("HaotianXu/changepoints")

Development version from HaotianXu/changepoints. 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-changepoints

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

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-changepoints

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-changepoints

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
