scores: Extract Scores and Loadings from PLSR and PCR Models

Description

These functions extract score and loading matrices from fitted mvr models.

Usage

loadings(object, ...)

# S3 method for default loadings(object, ...)

scores(object, ...)

# S3 method for default scores(object, ...)

Yscores(object)

loading.weights(object)

Yloadings(object)

Value

A matrix with scores or loadings.

Arguments

object

a fitted model to extract from.

...

extra arguments, currently not used.

Author

Details

All functions extract the indicated matrix from the fitted model, and will work with any object having a suitably named component.

The default scores and loadings methods also handle prcomp objects (their scores and loadings components are called x and rotation, resp.), and add an attribute "explvar" with the variance explained by each component, if this is available. (See explvar for details.)
