Each line is called a transaction and each column in a row represents an item. The data set is attached. Your assignment is to use R to mine the data for association rules. You should report support, confidence and lift and your top 10 rules by lift. Extra credit: do a simple cluster analysis on the data as well. Use whichever packages you like.
