Rules with multiple items in the RHS

[mhahsler]

Add code to produce rules with more than 1 items in the RHS in function ruleInduction().

I found this error doing an assignment that I could not finish because of it. I made a file to help but seem to confuse working on the package to wanting to install the package.

#would this work?

Install the devtools package if you haven't already

install.packages("devtools")

Fork the arules repository on GitHub and clone it to your local machine

Make modifications to the arules source code to handle multiple items on the RHS

Build and install the modified arules package

devtools::install("<path_to_your_local_arules_clone>")

Load the modified arules package

library(arules)

Function to perform rule induction with multiple items on RHS

ruleInduction <- function(data, min_support, min_confidence, rhs_items) {

Convert data to transactions

transactions <- read.transactions(data, format = "basket", sep = ",", cols = c("TransactionID", "Items"))

Mine association rules with modified apriori function

rules <- apriori(transactions, parameter = list(support = min_support, confidence = min_confidence), rhs_items = rhs_items)

Print the modified rules

print(rules)
}

Example usage

data <- "TransactionID,Items
1,A, B, C
2,A, B
3,B, C
4,A, C
5,B"

min_support <- 0.2
min_confidence <- 0.7
rhs_items <- c("B", "C")

Call the function

ruleInduction(data, min_support, min_confidence, rhs_items)

Do you have an implementation of rule induction with multiple items in the RHS?
