tidyRules.cubist {tidyrules}

Obtain rules as a tidy tibble from a cubist model

Description

Each row corresponds to a rule. A rule can be copied into 'dplyr::filter' to filter the observations corresponding to a rule

Usage

## S3 method for class 'cubist'
tidyRules(object, ...)

Arguments

object

Fitted model object with rules

...

Other arguments (currently unused)

Details

When col_classes argument is missing, an educated guess is made about class by parsing the RHS of sub-rule. This might sometimes not lead to a parsable rule.

Optional named arguments:

• language (string, default: "r"): language where the rules are parsable. The allowed options is one among: r, python, sql

Value

A tibble where each row corresponds to a rule. The columns are: support, mean, min, max, error, lhs, rhs and committee
