MassSpectrum-class: Mass spectrum objects

In kuwisdelu/MSExample: An example R package for mass spectrometry

Description

MassSpectrum is a simple S4 class designed to encapsulate basic information about a mass spectrum.

Usage

## S4 method for signature 'MassSpectrum'
mz(object, ...)

## S4 replacement method for signature 'MassSpectrum'
mz(object) <- value

## S4 method for signature 'MassSpectrum'
intensity(object, ...)

## S4 method for signature 'MassSpectrum'
peaks(object, ...)

## S4 method for signature 'MassSpectrum'
isCentroided(object, ...)

## S4 method for signature 'MassSpectrum'
tic(object, ...)

## S4 method for signature 'MassSpectrum'
length(x)

## S4 method for signature 'MassSpectrum'
x[i, j, ..., drop = TRUE]

Arguments

object	A MassSpectrum object
...	Additional arguments
value	A replacement value
x	A MassSpectrum object
i	indices specifying elements to extract
j	indices specifying elements to extract
drop	ignored

Methods (by generic)

• mz: Get m/z values

• mz<-: Set m/z values

• intensity: Get intensities

• peaks: Get indices of peaks

• isCentroided: Get whether the spectrum is centroided

• tic: Get the total ion count

• length: Get the length of the spectrum

• [: Subset a mass spectrum

Slots

mz

The m/z-values.

intensity

The intensities observed at the associated m/z values.

isCentroided

Whether the spectrum has been centroided or not.

peaks

The indices of any detected peaks
