Good morning

I am using Windows and the arules package to perform the Apriori. Please
see my code below:

library(arules)

tr<-read.transactions("apriori_data.txt",format="basket",sep=",")

rules <- apriori(tr, parameter= list(supp=0.00006, conf=0.05, minlen=4,
maxlen = 4))

inspect(rules)


WRITE(rules, file="rules_jb_2_to_1_lower.txt", sep=",", quote=FALSE)

Kind regards

Jolinda
