When calculating the frequent itemsets and rules, is possible to get the raw numbers needed to build a confusion matrix?

E.g.: After executing this:

frequent_itemsets = apriori(data, min_support=0.2, use_colnames=True)
rules = association_rules(frequent_itemsets, metric="support", min_threshold=0.2)

Is a way to build a confusion matrix like this?:

	C	not_C
A	A+C	A+not_C
not_A	not_A+C	not_A+not_C
