I am working on association rules that are considered outliers. I noticed that arules does not show results for rules that have a support less than .10. Is there any way that I could view rules that have a support of .1 (10%) or less?
I tried the following code to try to filter out rules with less than a .1 support. I suspect rules with less than a .1 support do not show up because there would be too many? In any case, here's the code I'm using to see rules with less than a .1 support. By the way, this code works when I want to see greater than anything over .1 .
rulesb = rulesa[quality(rulesa)$support<0.1]
From the examples in ?apriori:
data("Adult")
## Mine association rules.
rules <- apriori(Adult,
parameter = list(supp = 0.5, conf = 0.9, target = "rules"))
summary(rules)
Set supp to the value you like.
