require ("arules")
data ("Adult")
# The default support (0.1) yields ~6000 rules on Adult, and general.rules() compares every
# pair of them twice: that single call took more than 8 seconds. A higher support keeps the
# example instructive (169 rules, of which 8 are general) and instantaneous.
r = apriori (Adult, parameter = list (supp = .4, conf = .8))
inspect (general.rules (r))
