selectRefSp: Automated selection of a reference spectrum

In lhedjazi/mQTL.NMR: Metabolomic Quantitative Trait Locus Mapping for 1H NMR data

Description

Usage

selectRefSp(X, step)

Arguments

X	matrix of spectra
step	a numerical parameter used to scale spectral regions down to specific bin size

Value

returns the index of selected spectrum
