Overview

About

Maintained by Ruihan ZhangFirst published 2026-07-281 releasesCRAN page ↗GitHub ↗

We introduce a multi-study high-dimensional factor analysis toolbox 'MultiEFM' based on the elliptical factor model framework, which learns latent heterogeneous features and accounts for cross-study variation among sources. It provides robust estimation algorithms for heterogeneous datasets, particularly tailored for multi-study RNA sequencing arrays and complex spatial multi-omics layers. The package implements highly efficient initialization strategies, identifiability constraints alignment, and computationally scalable parameter estimation paradigms.

Install

R (CRAN)pak (dev)Fedora (COPR)

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

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

pak::pak("RRuihan-Zhang/MultiEFM")

Development version from RRuihan-Zhang/MultiEFM. Installs pak first if it is not already available.

# 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-MultiEFM

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