胁迫；“因素”；至；“交易”；使用Apriori时的R

我想对我的数据集上的“菜系”列执行Apriori方法

Cussine柱样品：

   [4] Japanese, Sushi                                                                   
   [5] Japanese, Korean                                                                  
   [6] Chinese                                                                           
   [7] Asian, European                                                                   
   [8] Seafood, Filipino, Asian, European                                                
   [9] European, Asian, Indian                                                           
  [10] Filipino                                                                          
  [11] Filipino, Mexican            

我的代码：

install.packages("arules") 
 library("arules")

 itemsets <- apriori(dataSet$Cuisines, parameter=list(support=0.02, minlen=1, maxlen=1, target="frequent itemsets"))

install.packages（“arules”）
图书馆（“阿鲁莱斯”）
itemsets您必须将数据转换为事务类型：

dats <- strsplit(as.character(dats$Cuisines),',',fixed=T) # split by comma    
trans <- as(dats, "transactions")
inspect(trans)
    items                               
[1] { Sushi,Japanese}                   
[2] { Korean,Japanese}                  
[3] {Chinese}                           
[4] { European,Asian}                   
[5] { Asian, European, Filipino,Seafood}
[6] { Asian, Indian,European}           
[7] {Filipino}                          
[8] { Mexican,Filipino}
