Usage

prepareTransactions(formula, data, disc.method = "mdlp", match = NULL)

Arguments

formula

the formula.

data

a data.frame with the data.

disc.method

Discretization method used to discretize continuous variables if data is a data.frame (default: "mdlp"). See discretizeDF.supervised for more supervised discretization methods.

match

typically NULL. Only used internally if data is a already a set of transactions.

Value

An object of class transactions from arules with an attribute called "disc_info" that contains information on the used discretization for each column.

# NOT RUN {
data("iris")

iris_trans <- prepareTransactions(Species ~ ., iris)
