mixmodMap_V2M: Vector of Labels to Matrix of Class Assignments Conversion

Description

Converts a vector of labels to a matrix of class assignments.

Usage

mixmodMap_V2M(z, n = length(z), K = max(z))

Arguments

z

vector of labels corresponding to the class assigned to each observation.

n

number of observations.

K

number of classes.

Value

matrix of class assignments. Rows correspond to observations and columns correspond to classes. Each row contains only zeros except for the column corresponding to the class to which the observation is assigned, which value is one.
