In kerntools: Kernel Functions and Tools for Machine Learning Applications

Convert categorical data to dummies.

Description

Given a matrix or data.frame containing character/factors, this function performs one-hot-encoding.

Usage

dummy_data(X, lev = NULL)

Arguments

X	A matrix, or a data.frame containing factors. (If the columns are of any other class, they will be coerced into factors anyway).
lev	(optional) A vector with the categories ("levels") of each factor.

Value

X (class: "matrix") after performing one-hot-encoding.

Examples

summary(CO2)
CO2_dummy <- dummy_data(CO2[,1:3],lev=dummy_var(CO2[,1:3]))
CO2_dummy[1:10,1:5]
