export-methods

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 signature 'AbstractMassObject'
export(x, file, type="auto", force=FALSE, ...)

## S4 method for signature '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`	`logical`, If `TRUE` the `file` would be overwritten or `path` would be created.
`path`	`character`, path to directory in which the `list` of `AbstractMassObject-class` would be exported.
`...`	arguments to be passed to specific export functions.

Details

Specific export functions:

tab	`exportTab`
csv	`exportCsv`
imzML	`exportImzMl`
msd	`exportMsd`
mzML	`exportMzMl`

Examples

## Not run: 
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")
