我已经成功安装包“arulesSequences”，可是函数cspade却用不了？？？这怎么办？高手帮帮忙，谢谢！
不知是否R语言版本问题？我的R语言版本是3.1.1。
library(arulesSequences)

tmp_data<-data.frame(item=factor(c("A","B","B","A","B","A","C","A","B","C","B","A","B","A","A","B","A","B")))#必须是factor
tmp_data.tran<-as(tmp_data,"transactions")
transactionInfo(tmp_data.tran)$sequenceID<-c(1,1,1,1,1,2,2,2,2,2,2,3,3,3,4,4,4,4)
transactionInfo(tmp_data.tran)$eventID<-c(10,10,20,30,30,20,20,30,30,30,50,10,30,40,30,30,40,50)
transactionInfo(tmp_data.tran)

#lab1：基本约束support（默认为0.1）
s_result<-cspade(tmp_data.tran,parameter = list(support = 0.75),control = list(verbose = TRUE))
inspect(s_result)

显示：
> s_result<-cspade(tmp_data.tran,parameter = list(support = 0.75),control = list(verbose = TRUE))
错误: 没有"cspade"这个函数
