Hi, I am wanting to look at frequent item sets using the arules package. I need to transform my data into a "transactions" object. The data I read in from a file has 2 columns, an ID and an item. How do I convert data like this into a transactions object?
I've tried class? transactions but it only confuses me. My data is like this.... basketID item 1 bread 1 cheese 1 milk 2 bread 2 cheese 2 eggs 3 bread 3 cheese 3 beer and from what I gather it should be like this? data <- list( c("bread","cheese","milk"), c("bread","cheese","eggs"), c("bread","cheese","beer") ) so I can use: t <- as(data, "transactions") Thanks in advance.
