In HDANOVA: High-Dimensional Analysis of Variance

Model Frame and Model Matrix for ASCA-like Models

Description

Extraction functions to retrieve the model.frame and model.matrix of an asca object.

Usage

## S3 method for class 'asca'
model.frame(formula, ...)

## S3 method for class 'asca'
model.matrix(object, ...)

Arguments

formula	The asca object.
...	Not implemented
object	The asca object.

Value

A data.frame or matrix object.

Examples

# Load candies data
data(candies)

# Basic ASCA model with two factors
mod <- asca(assessment ~ candy + assessor, data=candies)

# Extract model frame and model matrix
mf <- model.frame(mod)
head(mf)
mm <- model.matrix(mod)
par.old <- par(mar=c(3,3,3,1), mgp=c(1,0.7,0))
image(t(mm[seq(165,1,-1),]), main="Model Matrix", xlab="dummy values", ylab="samples",
     axes=FALSE)
par(par.old)
