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

Good morning,
1. What is your OS?
2. Which package do you use to perform the Apriori?
3. Without providing any reproducible code, it will probably be
complicated to answer you.
Best Regards

Good morning
When I try to run an Apriori, I keep often the following message:
checking subsets of size 1Error in apriori(tr, parameter = list(supp =
3e-05, conf = 0.05, minlen = 2, :
internal error in trio library
Other time it works fine on the same data. What can be the reason for
this?
