View source: R/proto.R

Description

This function extracts the prototype from each variable group.

Usage

1
proto(X, y, groups, type = c("max", "median"), mu = NULL)

Arguments

X

Predictor matrix

y

Response matrix with one column

groups

An group index vector containing the group number each variable belongs to. For example: c(1, 1, 1, 1, 1, 2, 2, 2, ...). Variable groups can be generated by the Fisher optimal partition algorithm implemented in FOP.

type

The rule for extracting the prototype. Possible options are "max" and "median".

mu

The mean value of y for standarization. Default is NULL, which uses the sample mean of y.

Value

The prototypes (variable index) extracted from each group (cluster).
