球球大神指导！在用R语言做关联性分析的时候，transactions函数总是出错！
我的代码是这样的：
library(xlsx)
read.xlsx2(file="C:\Users\18092\Desktop\LL.xlsx",sheetIndex=1)
library(arules)
library(arulesViz)#Load packages
dt<-read.table("C:/Users/18092/Desktop/LL.xlsx",header=T)#import data
LL<-as(dt,"transactions")#convert data.frame to transactions
rules=apriori("C:/Users/18092/Desktop/LL.xlsx",parameter=list(support=0.2,confidence=0.6,minlen=2,maxlen=2))#find association rules
summary(rules)
inspect(x[1:10])#show the first ten rules
错误是这样的：
library(arules)
library(arulesViz)#Load packages
dt<-read.table("C:/Users/18092/Desktop/LL.xlsx",header=T)#import data
