R : Subscript out of Bond using arule

Question

I'm using arules packages, and looking for rules I have this problem:

NB: txn is my transactions matrix

You can download here my CSV

My CVS File

convert csv file to basket format

library(arules)

txn = read.transactions(file="ItemList.csv", rm.duplicates= FALSE, format="basket",sep=",",cols=1);

remove quotes from transactions

txn@itemInfo$labels <- gsub("\"","",txn@itemInfo$labels)

rules <- apriori(txn,
                 parameter = list(support=.001,
                                  confidence=.5,
                                  minlen=2,
                                  target='rules' # to mine for rules
                 ))
>summary(rules)

... etc

> inspect(sort(rules, by='lift', decreasing = T)[1:5])
Error in slot(x, s)[i] : subscript out of bounds

At the end, My error is

Error in slot(x, s)[i] : subscript out of bounds

I read online that my problem should not come from a "wrong code" but from R settings. Thank you all for your help!

Just solved. Setting Support=0.00001 in rules makes everything work

rules <- apriori(txn,
                 parameter = list(support=.00001,
                                  confidence=.5,
                                  minlen=2,
                                  target='rules' # to mine for rules
                 ))
