For our business case, we'll focus on identifying the association rules for a grocery store. The dataset will be from the arules package and is called Groceries. This dataset consists of actual transactions over 30 days from a real-world grocery store and consists of 9,835 different purchases. All of the items purchased are put into one of 169 categories, for example, bread, wine, meat, and so on.
Let's say that we want to develop an understanding of what potential customers will purchase along with beer to identify the right product placement within the store or support a cross-selling campaign.
