This is done to allow for functions to be quickly identified and used\nthrough autocomplete inside of the [RStudio IDE](https://posit.co/products/open-source/rstudio/) or \n[VS Code](https://code.visualstudio.com/). At a later time, the `attribute_*()`\nwill likely be moved to a different package.\n\nFor more details, please see the [package vignettes](vignettes/):\n\n- [Overview of `simcdm`](https://tmsalab.github.io/simcdm/articles/overview-simcdm.html)\n- [Using `simcdm` in R packages](https://tmsalab.github.io/simcdm/articles/simcdm-in-packages.html)\n\n## Authors\n\nJames Joseph Balamuta and Steven Andrew Culpepper\nwith contributions from Aaron Hudson.\n\n## Citing the simcdm package\n\nTo ensure future development of the package, please cite `simcdm` package if \nused during the analysis or simulations.
