psymetrics 0.1.3

New Features

  • Enhanced Output Formats in print.model_fit and print.compare_model_fit: Added support for exporting tables in additional formats, including markdown and html, using the print.model_fit and print.compare_model_fit functions.
  • Customizable Alignment: Introduced the align argument to control table alignment in text and markdown formats. Available options include "left", "right", "center", and "firstleft". For more details, refer to the insight::export_table documentation.
  • Improved Error Handling: Functions now use cli::cli_abort for error handling, providing clearer and more detailed messages when unsupported parameters are passed.

Improvements

  • Code Refactoring: Made improvements to the structure of the print_format function and related code, optimizing format handling and code clarity.
  • Documentation Update: The documentation has been updated to reflect new parameters and features, including additional usage examples.

psymetrics 0.1.2

New Features

compare_model_fit() Function

  • Added: New function compare_model_fit() allows for comparing fit indices across multiple lavaan model objects.
  • Usage: You can pass multiple fitted lavaan model objects to compare_model_fit() and it will return a data frame with fit indices for each model, enabling easy comparison.
  • Verbose Option: Added a verbose argument to control the display of informational messages during comparison.
  • Print Method: Implemented a print.compare_model_fit method to provide a formatted output for easy reading of model comparisons.

Enhanced model_fit() Function

  • Updated: Improved the model_fit() function to handle multiple types of fit indices, including "standard", "scaled", and "robust".
  • Custom Metrics: Introduced the metrics argument, allowing users to specify exactly which fit indices they want to extract. If metrics is set to "essential", a predefined set of common indices is returned.
  • Verbose Option: Added a verbose argument to control the display of informational messages when metrics are adjusted according to the estimator type.
  • Print Method: Implemented a print.model_fit method to provide a clean and formatted output for the fit indices, with customizable precision.

Documentation

  • Updated: Improved the documentation for model_fit() and added comprehensive examples showcasing how to use compare_model_fit().

Note

  • Tests Pending: Unit tests for model_fit() and compare_model_fit() will be added in the next update to ensure consistent functionality and output formatting.

psymetrics 0.1.1

New Features

  • print.model_fit method: Added to format and display the results of the model_fit function.
    • The output format can be customized using the digits, p_digits, and format arguments.
    • Automatically formats the results using insight::format_table() and outputs them with insight::export_table().

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.
