In qCBA: Quantitative Classification by Association Rules

Description

Creates instance of arc CBAmodel class from the arc package Instance of CBAmodel can then be passed to qcba

Usage

arulesCBA2arcCBAModel(
  arulesCBAModel,
  cutPoints,
  rawDataset,
  classAtt,
  attTypes
)

Arguments

arulesCBAModel	aobject returned by arulesCBA::CBA()
cutPoints	specification of cutpoints applied on the data before they were passed to rCBA::build
rawDataset	the raw data (before discretization). This dataset is used to guess attribute types if attTypes is not passed
classAtt	the name of the class attribute

if (! requireNamespace("arulesCBA", quietly = TRUE)) {
 message("Please install arulesCBA: install.packages('arulesCBA')")
}  else {
 message("The following code might cause the 'pruning exception' rCBA error on some installations")
 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)
