Package: semEffect 1.3.0

semEffect: Unified Effect Analysis and Visualization for Structural Equation Models

Provides a unified interface to calculate, extract, and visualize standardized effect decompositions (direct, indirect, and total effects) for three major structural equation modeling (SEM) frameworks: 'lavaan', 'piecewiseSEM', and 'plspm'. The package simplifies comparative SEM analysis by offering consistent functions across different modeling paradigms. Key features include automated handling of zero-effect variables, generation of publication-ready 'ggplot2' visualizations, and returning both wide-format and long-format effect tables. It supports flexible effect filtering, accepts multi-model object inputs, and allows extensive customization of visualization parameters. The 'sem_modeling()' function serves as a central wrapper, enabling users to fit models using different packages with a unified syntax. For methodological background, see 'Rosseel' (2012) <doi:10.18637/jss.v048.i02> for 'lavaan', 'Lefcheck' (2016) <doi:10.1111/2041-210X.12512> for 'piecewiseSEM', and 'Sanchez' (2013) <doi:10.1007/s11747-012-0306-5> for 'PLS-PM'.
