Overview

About

Maintained by Julian D. KarchCRAN page ↗GitHub ↗Website ↗Issues ↗

Provides a graphical user interface with an integrated diagrammer for latent variable models from the 'lavaan' package. It offers two core functions: first, lavaangui() launches a web application that allows users to specify models by drawing path diagrams, fitting them, assessing model fit, and more; second, plot_lavaan() creates interactive path diagrams from models specified in 'lavaan'. After customizing a diagram interactively, export_plot() saves it to a file, enabling reproducible scripts without sacrificing fine-grained control over appearance. Karch (2024) <doi: 10.1080/10705511.2024.2420678> contains a tutorial.

Changes in 0.4.0

Added: export_plot() function to export the graph as PNG, JPEG, SVG, or PDF
Added: plot_lavaan() now saves and restores the layout and viewport between sessions.
Added: Full composite variable support — composites are their own class with a hexagonal node shape.
Added: Lavaan labels and display labels are now distinguished; display labels can be edited independently. Display labels support simple math/LaTeX-style notation and multi-line text.
Added: Option to hide undirected edges.
Added: Reset button to restore the default state.
Added: Variable selector for model templates validates that selected variables are still available.
Added: Package-level documentation page.
Bugfix: Grid options were not saved with the model file.
Bugfix: Serialization/state bug in model save and load.
Bugfix: Minor bug in lavInspect output handling.
Bugfix: Divider in context menu was not rendered correctly.

Bugfix: Guard added for undefined nodes in cycle detection.
Security: Removed use of eval() on the server side.
Appearance: Removed the linked/not-linked visual distinction for observed nodes.
Developer: Detection of local vs. shinyapps.io deployment now uses the where command; Heroku support removed.

Install

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

install.packages("lavaangui", 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("karchjd/lavaangui")

Development version from karchjd/lavaangui. 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-lavaangui

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-lavaangui

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-lavaangui

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.
