I tried using the apriori algorithm in the arules library for association rules mining in R. There's two thing I'd like to ask:
Why are the lhs and rhs of the rules in intervals? For example U get something like this lhs : Variable1[0,4] - rhs : Variable2[0,3]
How can I subset the rules extracted for a certain variable? Say I want rules for Variable 1. How can I subset the result to get rules containing that variable only?
