Examples

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

inspectDT(rules)

# for more control on the data table, you can used DATAFRAME() to convert the rules.
rules_df <- DATAFRAME(rules, setStart = "", setEnd = "", itemSep = " + ")
rules_df$count <- NULL
head(rules_df)
inspectDT(rules_df)

# Save HTML widget as web page
p <- inspectDT(rules)
htmlwidgets::saveWidget(p, "arules.html", selfcontained = FALSE)
# Note: self-contained seems to make the browser slow.

# inspect the widget
browseURL("arules.html")

# clean up
unlink(c("arules.html", "arules_files"), recursive = TRUE)
