disc.ef: Discretization using the method of equal frequencies

Description

Unsupervised discretization using intervals of equal frequencies

Usage

disc.ef(data, varcon, k,out=c("symb","num"))

Arguments

data

The dataset to be discretized

varcon

A vector containing the continuous features

k

The number of intervals to be used

out

To get the discretized dataset in a numerical format write "num". To get the discretized in an interval format write "symb"

Value

Returns a new data matrix with discretized values.
