rules

Introduction

rules is a parsnip 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 with:

install.packages("rules")

Install the development version from GitHub with:

# install.packages("pak")
# pak::pak("tidymodels/rules")
install.packages("rules", repos = c('https://tidymodels.r-universe.dev', 'https://cloud.r-project.org'))

Available Engines

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

model	engine	mode
C5_rules	C5.0	classification
cubist_rules	Cubist	regression
rule_fit	xrf	classification
rule_fit	xrf	regression
