与规则包R中的％in％匹配的交易 [英] matching transaction with %in% in arules package R

问题描述

我需要找到符合某些规则的交易. 以下代码曾经可以使用，但是现在R从基本包中识别出%in%，而不是从 arles 中识别出.

I need to find transactions matching some rules. The following code used to work, but now R recognise %in% from the base package instead from arules.

matchRules=function(rules,transactions){
  id.match=which(transactions %in% rules)
  matchedTrx=transactions[id.match]
  summary(matchedTrx)

  return(matchedTrx)
}

我尝试了arules::%in%，但是它不起作用.

I tried arules::%in% but it doesn't work.

如果我使用:

id.match=which(transactions arules::%in% rules)

我收到错误消息:

unexpected symbol in "id.match=which(transactions arules"

感谢您的帮助.

推荐答案

尝试使用此方法代替％in％，希望对您有所帮助

Try this instead of %in%, I hope it helps

library(arules)    
st <- supportingTransactions(rules, transactions)
Transaction_IDs <- as(st,"list")
