this is a special question and since I have been for lot of weeks of research I didn't found any answer.
The dataset is Groceries I get with this commands:
install.packages("arules")
library(arules)
data(Groceries)
I try to show the number of transactions that have n items them (in R with R Studio). I am completely stuck. I though at first creating a rule.... but I'm still stuck at this step.
Can someone help me?
Thank you in advance!
This should do it! Let me know if this is what you meant!
n_items <- 4
large_transactions <- Groceries[size(Groceries) > n_items]
