createMassPeaks-functions

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.
