The formulaic package creates a\nunified approach for programmatically and dynamically\ngenerating formula objects. Users may specify the outcome and\ninputs of a model directly, search for variables to include\nbased upon naming patterns, incorporate interactions, and\nidentify variables to exclude. A wide range of quality checks\nare implemented to identify issues such as misspecified\nvariables, duplication, a lack of contrast in the inputs, and a\nlarge number of levels in categorical data. Variables that do\nnot meet these quality checks can be automatically excluded\nfrom the model. These issues are documented and reported in a\nmanner that provides greater accountability and useful\ninformation to guide an investigation of the data.", "URL":
