if (! requireNamespace("arulesCBA", quietly = TRUE)) {
 message("Please install arulesCBA: install.packages('arulesCBA')")
}  else {
if (FALSE) {
 classAtt <- "Species"
 discrModel <- discrNumeric(iris, classAtt)
 irisDisc <- as.data.frame(lapply(discrModel$Disc.data, as.factor))
 arulesCBAModel <- arulesCBA::CBA(Species ~ ., data = irisDisc, supp = 0.1, 
  conf=0.9)
 CBAmodel <- arulesCBA2arcCBAModel(arulesCBAModel, discrModel$cutp,  iris, classAtt)
 qCBAmodel <- qcba(cbaRuleModel=CBAmodel,datadf=iris)
 print(qCBAmodel@rules)
