export,AbstractMassObject-method: Export files

Description

This function provides a general interface to export AbstractMassObject-class objects (e.g. MassSpectrum-class, MassPeaks-class) into different file formats.

Usage

# S4 method for AbstractMassObject
export(x, file, type="auto", force=FALSE, ...)
# S4 method for list
export(x, path, type, force=FALSE, ...)

Arguments

x

a AbstractMassObject-class object or a list of AbstractMassObject-class objects.

file

character, file name.

type

character, file format. If type is set to “auto” the file extension is used.

force

Examples

if (FALSE) {
library("MALDIquant")
library("MALDIquantForeign")

s <- list(createMassSpectrum(mass=1:5, intensity=1:5),
          createMassSpectrum(mass=1:5, intensity=1:5))

## export a single spectrum
export(s[[1]], file="spectrum.csv")
## identical to exportCsv(s[[1]], file="spectrum.csv")

## export a list of spectra
export(s, path="spectra", type="csv")
## identical to exportCsv(s, path="spectra")
