Usage

## S3 method for class 'AbstractMassObject':
exportTab(x, file,
    force=FALSE, \ldots)
  ## S3 method for class 'list':
exportTab(x, path, force=FALSE, \ldots)
  ## S3 method for class 'AbstractMassObject':
exportCsv(x, file,
    force=FALSE, \ldots)
  ## S3 method for class 'list':
exportCsv(x, path, force=FALSE, \ldots)

Arguments

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

exportTab and exportCsv use write.table with different defaults (

sep="" in exportTab and sep=","
  in exportCsv).

library("MALDIquant") library("MALDIquantForeign")

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

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

## export a list of spectra and use ; as separator exportCsv(s, path="spectra", sep=";", force=TRUE)
