full_factorial: Full Factorial Design

In JedStephens/ExpertChoice: Design of Discrete Choice and Conjoint Analysis

Description

Generates the full factorial design with all the factors coded using standardised orthogonal contrast coding.

Usage

full_factorial(attributes_list)

Arguments

attributes_list

A named list: giving the variable name and the levels as characters. The levels should start from the base of either "0" or "1" and go up in integer values.

Value

a 'data.frame' with the full factorial design and factors coded using standardised orthogonal contrast coding.
