R Basket analysis using arules package with unique order number but duplicate order combinations Just learning R. I'm trying to do a basket analysis using the arules package (but I'm totally open to any other package suggestions!) to compare all possible combinations of 6 different item types being purchased. My original data set looked like this: OrderNo, ItemType, ItemCount 111, Health, 1 111, Leisure, 2 111, Sports, 1 222, Health, 3 333, Food, 7 333, Clothing, 1 444, Clothing, 2 444, Health, 1 444, Accessories, 2 . . . the list goes on and has about 3,000 observations. I collapsed the data

Ok, so I have searched a lot and want to run arules on sales data. I just need to properly get the data in the right format and set up with the correct "factors" or "variables" and in basket form. Right now I have sales data with the Order# and then the items inside that. Each order is unique (every new order, a new # gets created and includes the part#), but the same items obviously can appear in many orders. Currently, my data is set up like this: Order# Part# PartDescription 1 A PartA 1 B PartB 1 G PartG 2 R PartR 3 A PartA 3 B PartB 4 E PartE 5 Y PartY 6 A PartA 6 B PartB 6 F PartF 6 V
