Overview

About

Maintained by Abdullah Faruk KILICCRAN page ↗GitHub ↗Issues ↗

Provides a comprehensive Shiny-based graphical user interface for conducting a wide range of factor analysis procedures. 'FAfA' (Factor Analysis for All) guides users through data uploading, assumption checking (descriptive statistics, collinearity, multivariate normality, outliers), data wrangling (variable exclusion, data splitting), exploratory factor analysis (EFA) with various rotation and extraction methods, confirmatory factor analysis (CFA), reliability analysis (e.g., Cronbach's Alpha, McDonald's Omega), and measurement invariance testing across groups. Factor retention methods include parallel analysis following Horn (1965) doi:10.1007/BF02289447, optimized parallel analysis following Timmerman and Lorenzo-Seva (2011) doi:10.1037/a0023353, permutation parallel analysis for categorical variables following Lubbe (2019) doi:10.1037/met0000171, the Hull method following Lorenzo-Seva et al. (2011) doi:10.1080/00273171.2011.564527, minimum average partial criteria following Velicer (1976) doi:10.1007/BF02293557 and O'Connor (2000) doi:10.3758/BF03200807, and the empirical Kaiser criterion following Braeken and van Assen (2017) doi:10.1037/met0000074. Exploratory graph analysis follows Golino and Epskamp (2017) doi:10.1371/journal.pone.0174035, with bootstrap stability assessment following Christensen and Golino (2021) doi:10.3390/psych3030032. Internal split-sample EFA replication follows Osborne and Fitzpatrick (2012) doi:10.7275/h0bd-4d11. Model-specific dynamic fit index cutoffs for CFA follow McNeish and Wolf (2023) doi:10.1037/met0000425. Item weighting follows Kılıç (2026) doi:10.3758/s13428-026-03095-w. Analyses use established R packages such as 'lavaan' and 'psych'. Results are presented in tables and plots with downloadable outputs. Analysis projects can be saved and restored, and reproducible R, HTML, and PDF workflow reports can be generated.

Changes in 1.4.1

Increased the package version for resubmission after CRAN reported that submitted version 1.4 was not newer than existing version 1.4.
Clarified the descriptive-statistics wording in DESCRIPTION and completed the spelling dictionary for the cited author names.
Updated application version labels and desktop package metadata to 1.4.1.
Enabled incoming feasibility checks and required suggested dependencies in the default local package check, using CRAN test settings and checking the PDF manual.
Replaced obsolete README check failures from version 0.5 with current package-check instructions and synchronized the golem configuration version.

From NEWS.md in the release

Install

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

install.packages("FAfA", 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("AFarukKILIC/FAfA")

Development version from AFarukKILIC/FAfA. 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-fafa

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-FAfA

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-FAfA

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.
