Error saying "Error in df$item : object of type 'closure' is not subsettable" when trying to use arules package

0 votes

I'm trying to find frequent itemsets of a data set using arules package .i found this example but it doesn't work for me .

ID <- c("A123","A123","A123","A123","B456","B456","B456")
item <- c("bread", "butter", "milk", "eggs", "meat","milk", "peas")

df <- data.frame(ID = ID, item = item)

library(arules)

trans <- as(split(df$item, df$ID), "transactions")

the result that i want is :

#   items                    transactionID
# 1 {bread,butter,eggs,milk} A123         
# 2 {meat,milk,peas}         B456 

i'm getting this error :"Error in df$item : object of type 'closure' is not subsettable"

Try replacing

ID <- c("A123","A123","A123","A123","B456","B456","B456")
item <- c("bread", "butter", "milk", "eggs", "meat","milk", "peas")
df <- data.frame(ID = ID, item = item)

with

ID=c("A123","A123","A123","A123","B456","B456","B456")
item=c("bread", "butter", "milk", "eggs", "meat","milk", "peas")
trans <- as(split(df$item, df$ID), "transactions")
