baseline (version 1.3-1)

runTest: Run a predictionTest or baselineAlgTest

Description

Runs the test defined in a '>predictionTest or '>baselineAlgTest object

Usage

runTest(object, X, y, ...)
# S4 method for PLSRTest
runTest(object, X, y)
# S4 method for ridgeRegressionTest
runTest(object, X, y)
# S4 method for baselineAlgTest
runTest(object, X, y, predictionTest, postproc, verbose = FALSE)

Arguments

object

An object of class '>baselineAlgTest or subclass of '>predictionTest (currently '>PLSRTest or '>ridgeRegressionTest). The object specify the test to be run

X

A matrix. The spectra to use in the test

y

A vector or matrix. The response(s) to use in the test

predictionTest

A '>predictionTest object, describing the prediction test to use for this baseline algorithm test

postproc

A function, used to postprocess the baseline corrected spectra prior to prediction testing. The function should take a matrix of spectra as its only argument, and return a matrix of postprocessed spectra

verbose

Logical, specifying whether the test should print out progress information. Default is FALSE

…

Other arguments. Currently only used by the '>baselineAlgTest method.

Value

runTest returns an object of class '>predictionResult or '>baselineAlgResult.

Methods

signature(object = "baselineAlgTest")

Baseline corrects the spectra, optionally postprocesses them, and runs a prediction test on the corrected spectra.

signature(object = "PLSRTest")

Runs PLSR on the data and calculates the cross-validated RMSEP

signature(object = "ridgeRegressionTest")

Runs ridge regression on the data and calculates the GCV
