lessSEM: Non-Smooth Regularization for Structural Equation Models

Provides regularized structural equation modeling (regularized SEM) with non-smooth penalty functions (e.g., lasso) building on 'lavaan'. The package is heavily inspired by the ['regsem'](<https://github.com/Rjacobucci/regsem>) and ['lslx'](<https://github.com/psyphh/lslx>) packages.

Version:	1.5.7
Depends:	R (≥ 4.1.0), lavaan, methods
Imports:	Rcpp (≥ 1.0.8), RcppArmadillo, RcppParallel, ggplot2, ggrepel, tidyr, stringr, numDeriv, utils, stats, graphics, rlang, mvtnorm
LinkingTo:	Rcpp, RcppArmadillo, RcppParallel
Suggests:	knitr, plotly, rmarkdown, Rsolnp
