createMassPeaks-functions: Creates a MassPeaks object.

In MALDIquant: Quantitative Analysis of Mass Spectrometry Data

Creates a MassPeaks object.

Description

This function creates a MassPeaks object. Normally it shouldn't called by the user. Try detectPeaks,MassSpectrum-method instead.

Usage

createMassPeaks(mass, intensity, snr=rep.int(NA_real_, length(intensity)),
                metaData=list())

Arguments

mass	vector, mass or mass-to-charge ratio.
intensity	vector, intensities for measured mass-to-charge ratios.
snr	vector, signal-to-noise ratios for intensity values.
metaData	list, some metadata to describe the peaks.

Value

Returns a MassPeaks object.
