[+] Reconstruct spectra from loadings and scores (i.e. components and amplitudes)

Description

Reconstruct spectra from loadings and scores (i.e. from spectroscopic components and their amplitudes).

Usage

reconstructSp(loadings, scores, sp = NULL)

Arguments

loadings	Components' spectra (loadings) as either a matrix or a hyperSpec object.
scores	Components' amplitudes (scores) as either a matrix or a hyperSpec object.
sp	hyperSpec object which has the same number or rows as scores. If sp is provided, reconstructed spectra will replace other spectroscopic data in sp. This object will be returned as a result of this function.

Value

Reconstruction of the original spectroscopic data matrix, based on scores and loadings as either a matrix or hyperSpec object.
reconstructed <- scores %*% loadings
