Overview

About

Maintained by Kabir Opeyemi OloredeCRAN page ↗GitHub ↗Issues ↗

Implements shrinkage principal fitted components for sufficient dimension reduction in high-dimensional regression and classification. Provides regularised covariance estimation using Oracle Approximating Shrinkage and Maximum Entropy Covariance, structural-dimension selection using conventional and information-complexity criteria, response-guided feature screening, reduced-space prediction, and simulation utilities. Methodological foundations include Cook and Forzani (2008) doi:10.1214/08-STS275, Chen et al. (2010) doi:10.1109/TSP.2010.2053029, Bozdogan (2000) doi:10.1006/jmps.1999.1277, and Olorede and Yahya (2019) doi:10.48550/arXiv.1909.13017.

Changes in 0.1.0

Began GitHub and CRAN release hardening without changing the statistical methodology or thesis-result implementation.
Added repository metadata, README, citation metadata, and CRAN-preparation notes.
Excluded thesis-analysis artefacts and exploratory outputs from the CRAN source tarball while retaining them for GitHub reproducibility.
Replaced over-strong public wording about sparsity/selection with feature-screening terminology where appropriate.
Removed third-party Riboflavin and Golub benchmark copies from the distributable package; the GitHub thesis-analysis layer now obtains Riboflavin from the archived CRAN hdi 0.1-10 source (with an installed-hdi fast path when available) and Golub from Bioconductor multtest when empirical reproduction is requested.
Passed a local CRAN-style check with 0 errors, 0 warnings, and 0 notes and established a five-platform GitHub Actions R CMD check workflow.
Hardened validation stratification so numeric binary responses are treated as categorical strata in train-test splitting and cross-validation fold construction.
Added regression tests for numeric binary-response stratification without changing the statistical methodology or thesis-result implementation.
Verified 149/149 local tests, a local R CMD check with 0 errors, 0 warnings, and 0 notes, exact R 3.5.0 compatibility, and the five-platform GitHub Actions matrix at commit fc80e696b7a64a2b8ab7c274f0af6c13e0fbb8ff.
Made citation metadata safe to evaluate before package installation by removing the runtime package-description lookup.
Declared British English and added a reviewed spelling wordlist for technical terms, acronyms, proper names, and method identifiers.
Built and verified the exact 0.1.0 source tarball with 149/149 test expectations passing, no spelling flags, no missing or forbidden source-package entries, and a Windows R 4.6.0 R CMD check result of 0 errors, 0 warnings, and 0 notes.

From NEWS.md in the release

Install

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

install.packages("spfcICOMP", 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("ilovemaths/spfcICOMP")

Development version from ilovemaths/spfcICOMP. 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-spfcicomp

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-spfcICOMP

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-spfcICOMP

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.
