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)
from arules.
Do you have an implementation of rule induction with multiple items in the RHS?
