In RulesTools: Preparing, Analyzing, and Visualizing Association Rules

Compare Association Rule Sets and Find Their Intersections

Description

Compares multiple sets of association rules, identifies intersections, and optionally displays the results or writes them to a CSV file.

Usage

compare_rules(..., display = TRUE, filename = NULL)

Arguments

...	Named association rule sets (objects of class rules).
display	Logical. If TRUE, prints the intersection results. Default is TRUE.
filename	Character string. If provided, writes the results to a CSV file. Default is NULL.

Value

A list containing the intersections of the provided rule sets.

Examples

library(arules)
data(BrookTrout)

# Discretize the BrookTrout dataset
discrete_bt <- dtize_df(BrookTrout, cutoff = "mean")

# Generate the first set of rules with a confidence threshold of 0.5
rules1 <- apriori(
  discrete_bt,
  parameter = list(supp = 0.01, conf = 0.5, target = "rules")
)

# Generate the second set of rules with a higher confidence threshold of 0.6
rules2 <- apriori(
  discrete_bt,
  parameter = list(supp = 0.01, conf = 0.6, target = "rules")
)

# Compare the two sets of rules and display the intersections
compare_rules(
  r1 = rules1,
  r2 = rules2,
  display = TRUE
)

# If `filename = "intersections.csv"`, the data is saved in a .csv file
