Overview

About

Maintained by Youzhi YuFirst published 2022-02-243 releasesCRAN page ↗GitHub ↗

R provides fantastic tools for changepoint analysis, but plots generated by the tools do not have the 'ggplot2' style. This tool, however, combines 'changepoint', 'changepoint.np' and 'ecp' together, and uses 'ggplot2' to visualize changepoints. It provides a unified 'ggcpt' S3 result class, 'broom'-style tidy/glance/augment methods, 'autoplot()', composable geoms ('geom_changepoint()', 'geom_cpt_segment()', 'geom_cpt_ci()', 'stat_changepoint()'), a unified 'cpt_detect()' dispatcher with method introspection via 'cpt_methods()', wrappers for several optional engines (WBS, WBS2, NOT, MOSUM, FPOP, Isolate-Detect, TGUH), a method comparison module, accuracy metrics, data simulation, and canonical test signals.

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-ggchangepoint

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-ggchangepoint

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-ggchangepoint

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