psymetrics 0.1.0

New Features

• model_fit.lavaan function: Implemented to extract fit indices from models created with lavaan.

  • Supports three types of fit indices: standard, scaled, and robust.
  • Allows users to specify custom metrics using the metrics argument.
  • Provides informative messages regarding the automatic adjustment of metrics (scaled or robust) based on the estimator used.

• model_fit function: Added as a generic function for extracting model fit indices. Currently implemented for objects of class lavaan.

Bug Fixes

• Fixed the S3 method consistency issue between model_fit and model_fit.lavaan.
• Corrected the declaration of dependencies in the DESCRIPTION file to include rlang under Suggests.

Notes

• The NAMESPACE file is now automatically managed using roxygen2 to export the appropriate functions and maintain dependency order.
• Added a check in the examples to verify if lavaan is installed before running them.
