createMassPeaks {MALDIquant}

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.
