Overview

About

Maintained by Johannes KarlCRAN page ↗GitHub ↗Issues ↗

Combines multiple functions that automate and simplify methods commonly employed in cross-cultural psychology, providing a unified analysis approach for measurement invariance testing, effect sizes for differential item functioning, factor congruence and multi-group reliability. Methods follow Fischer and Karl (2019) doi:10.3389/fpsyg.2019.01507 and Gunn, Grimm and Edwards (2020) doi:10.1080/10705511.2019.1689507.

Changes in 0.2.8

CRAN compliance

Removed the dependency on **ufs**, which is scheduled for archival on CRAN. mg_rel_table() no longer calls ufs::scaleStructure(); the internal consistency measures are now computed inside ccpsyc using **lavaan** and **psych**, both of which were already imported.
clearing_fa() no longer calls xlsx::read.xlsx(). The **xlsx** package was not declared in Imports, which caused an undeclared-dependency check failure. Excel key files are now read with **readxl** (moved to Suggests), which also removes the Java requirement. Supplying an .xlsx key file without readxl installed now raises an informative error.
calculate_dif_indices() is now actually exported and documented; it was tagged for export but missing from NAMESPACE.

Declared stats in Imports and dropped the unused rlang dependency.
Removed the redundant data/example.csv, which duplicated data/example.rda and defined the same example object.

Bug fixes

release_bonferroni() passed the rlang .data pronoun as a data argument to dplyr::filter(), causing the function to error.
splitgroup() used an invalid column selection that could not work as written; it now drops the grouping column and returns the remaining ones.
pancultural() signalled an error with print() rather than stop(), and coerced nfactors to character before passing it to psych::principal().
gamma_hat_scaled() no longer computes an unused quantity.

Changes in reported statistics

The glb column of mg_rel_table() now reports the maximum split-half reliability (Guttman's lambda 4) via psych::splitHalf(). The previous route, psych::glb(), calls psych::ICLUST(), which draws a diagram even when plot = FALSE and therefore fails whenever no graphics device has been initialised. Values are very close to, but not always identical to, those reported previously.
Alpha and omega confidence intervals are now computed analytically rather than through the previous wrapper. Alpha reproduces the normal-theory interval exactly; omega is estimated from a single-factor congeneric model with a delta-method interval. The seed argument of mg_rel_table() is retained for backward compatibility but is no longer used, and a conf.level argument has been added.
Measures that cannot be estimated for a group (fewer than three items, or a model that fails to converge) now return NA instead of erroring.

Documentation and tests

Added runnable examples for dMACS(), mg_rel_table() and calculate_dif_indices().
Internal helpers MNCI() and gamma_hat_scaled() are no longer given .Rd pages, which lacked \value sections.
Added tests for mg_rel_table() and added tolerances to the existing numerical tests so they are robust across BLAS implementations.

From NEWS.md in the release

Install

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

install.packages("ccpsyc", 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("Jo-Karl/ccpsyc")

Development version from Jo-Karl/ccpsyc. 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-ccpsyc

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-ccpsyc

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-ccpsyc

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.
