R package arules - Mining Association Rules and Frequent Itemsets

Maintainer: Michael Hahsler

Introduction

The arules package family for R provides the infrastructure for representing, manipulating and analyzing transaction data and patterns using frequent itemsets and association rules. The package also provides a wide range of interest measures and mining algorithms including the code of Christian Borgelt’s popular and efficient C implementations of the association mining algorithms Apriori and Eclat. In addition, the following mining algorithms are available via fim4r:

Code examples can be found in Chapter 5 of the web book R Companion for Introduction to Data Mining.

Usage

Load package and mine some association rules.

library("arules")
data("IncomeESL")

trans <- transactions(IncomeESL)
trans
## transactions in sparse format with
##  8993 transactions (rows) and
##  84 items (columns)
rules <- apriori(trans, supp = 0.1, conf = 0.9, target = "rules")
