## Introduction

rules is a [parsnip](https://parsnip.tidymodels.org/) extension package with model definitions for rule-based models, including:

* cubist models that have discrete rule sets that contain linear models with an ensemble method similar to boosting
* classification rules where a ruleset is derived from an initial tree fit
* _rule-fit_ models that begin with rules extracted from a tree ensemble which are then added to a regularized linear or logistic regression.

## Installation

You can install the released version of rules from [CRAN](https://CRAN.R-project.org) with:

``` r
install.packages("rules")
```

Install the development version from GitHub with:

``` r
# install.packages("pak")
pak::pak("tidymodels/rules")
```

## Available Engines

The rules package provides engines for the models in the following table.

```{r}
#| echo: false
#| message: false
library(parsnip)

parsnip_models <- setNames(nm = get_from_env("models")) |>
purrr::map_dfr(get_from_env, .id = "model")

library(rules)

rules_models <- setNames(nm = get_from_env("models")) |>
purrr::map_dfr(get_from_env, .id = "model")

dplyr::anti_join(
rules_models, parsnip_models,
by = c("model", "engine", "mode")
) |>
knitr::kable()
```
