mkIndiList {anacor}R Documentation

Converts Table to Indicator Matrix

Description

This function takes a data frame, a vector of types, a list of knot vectors, and a vector of orders. It returns a list of codings for the variables, i.e., crisp indicator, numerical version, or fuzzy indicator.

Usage

mkIndiList(data, type = rep("C",dim(data)[2]), knots = repList(0,length(type)),
ord = rep(1,length(type)))

Arguments

data Data frame to be converted.
type If "C", a crisp indicator is returned; if "A", a numerical version; if "F", the b-spline basis as a fuzzy indicator.
knots Knot sequence for type-C coding.
ord Variable order for type-C coding.
