Maintained by Paul BrooksCRAN page ↗

Implementations of several methods for principal component analysis using the L1 norm. The package depends on COIN-OR Clp version >= 1.17.4. The methods implemented are PCA-L1 (Kwak 2008) DOI:10.1109/TPAMI.2008.114, L1-PCA (Ke and Kanade 2003, 2005) DOI:10.1109/CVPR.2005.309, L1-PCA* (Brooks, Dula, and Boone 2013) DOI:10.1016/j.csda.2012.11.007, L1-PCAhp (Visentin, Prestwich and Armagan 2016) DOI:10.1007/978-3-319-46227-1_37, wPCA (Park and Klabjan 2016) <DOI: 10.1109/ICDM.2016.0054>, awPCA (Park and Klabjan 2016) <DOI: 10.1109/ICDM.2016.0054>, PCA-Lp (Kwak 2014) DOI:10.1109/TCYB.2013.2262936, and SharpEl1-PCA (Brooks and Dula, submitted).

From NEWS in the release

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)

install.packages("pcaL1", repos = "https://cloud.r-project.org/")

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

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-pcal1

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-pcaL1

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

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