Introduction

This R package extends package arules with various visualization techniques for association rules and itemsets. The package also includes several interactive visualizations for rule exploration.

The following R packages use arulesViz: arules, fdm2id, rattle, TELP

This might also require the development version of arules.

Features

• Visualizations using engines ggplot2 (default engine for most methods), grid, base (R base plots), htmlwidget (powered by plotly and visNetwork).
• Interactive visualizations using grid, plotly and visNetwork.
• Interactive rule inspection with datatable.
• Integrated interactive rule exploration using ruleExplorer.

Available Visualizations

• Scatterplot, two-key plot
• Matrix and matrix 3D visualization
• Grouped matrix-based visualization
• Several graph-based visualizations
• Doubledecker and mosaic plots
• Parallel Coordinate plot

Installation

Stable CRAN version: Install from within R with

install.packages("arulesViz")

Current development version: Install from r-universe.

install.packages("arulesViz",
    repos = c("https://mhahsler.r-universe.dev",
              "https://cloud.r-project.org/"))

Usage

Mine some rules.

library("arulesViz")
data("Groceries")
rules <- apriori(Groceries, parameter = list(support = 0.005, confidence = 0.5))
