filterRules: Post process association rules

In brooksandrew/Rsenal: Rsenal (arsenal) of assorted R functions developed over the years

Description

This function filters rules that have already been mined.

Usage

filterRules(rules, oneSideOnly = oneSideOnly)

Arguments

rules	list of association rules (S4 arules object). Output of apriori function.
oneSideOnly	list of character vectors. Each character vector of the list contains variables that are likely very similar and will generate uninteresting rules. So the filtering algorithm will prune rules where variables within this list appear on both the RHS & LHS

Value

association rules

Examples

library('arules')
data('Adult')
rules <- apriori(Adult, parameter = list(supp=0.01, conf=0.9, target = "rules"))
oneSideOnly <- list(c('age', 'workclass', 'education'), c('marital-status', 'occupation', 'race'))
f2 <- filterRules(rules, oneSideOnly=oneSideOnly)
length(rules)
length(f2)
