exportMsd-methods

Export to MSD files

Description

This function exports AbstractMassObject-class objects (e.g. MassSpectrum-class, MassPeaks-class) into mMass MSD files.

Usage

## S4 method for signature 'MassSpectrum'
exportMsd(x, file, force=FALSE, peaks, ...)

## S4 method for signature 'list'
exportMsd(x, path, force=FALSE, peaks, ...)

Arguments

`x`	a `MassSpectrum-class` object or a `list` of `MassSpectrum-class` objects.
`file`	`character`, file name.
`force`	`logical`, If `TRUE` the `file` would be overwritten or `path` would be created.
`peaks`	a `MassPeaks-class` object or a `list` of `MassPeaks-class` objects.
`path`	`character`, path to directory in which the `list` of `AbstractMassObject-class` would be exported.
`...`	arguments to be passed to `write.table`.

Examples

## Not run: 
library("MALDIquant")
library("MALDIquantForeign")

s <- list(createMassSpectrum(mass=1:5, intensity=1:5),
          createMassSpectrum(mass=1:5, intensity=1:5))
p <- list(createMassPeaks(mass=4:5, intensity=4:5, snr=1:2),
          createMassPeaks(mass=4:5, intensity=4:5, snr=1:2))

## export a single spectrum
exportMsd(s[[1]], file="spectrum.msd")

## export a single spectrum with corresponding peaks
exportMsd(s[[1]], file="spectrum.msd", peaks=p[[1]])

## export a list of spectra with corresponding peaks
exportMsd(s, path="spectra", peaks=p, force=TRUE)

## End(Not run)
