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.
