In resemble: Memory-Based Learning in Spectral Chemometrics

Projection function for the opls function

Description

Projects new spectra onto a PLS space based on a model generated by either by opls or the opls2 functions. For internal use only!.

Usage

project_opls(projection_mat, ncomp, newdata, scale, Xcenter, Xscale)

Arguments

projection_mat	the projection matrix generated by the opls function.
ncomp	an integer value indicating how may components must be used in the prediction.
newdata	a matrix containing the predictor variables.
scale	a logical indicating whether the matrix of predictors used to create the regression model was scaled.
Xcenter	a matrix of one row with the values that must be used for centering newdata.
Xscale	if scale = TRUE a matrix of one row with the values that must be used for scaling newdata.

Value

a matrix corresponding to the new spectra projected onto the PLS space
