disc.ew: Discretization using the equal width method

Description

Unsupervised discretization using intervals of equal width. The widths are computed using Scott's formula.

Usage

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

Arguments

data

The name of the dataset containing the attributes to be discretized

varcon

A vector containing the indexes of the attributes to be discretized

out

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