writeEset {ptairMS} | R Documentation

## Exporting an ExpressionSet instance into 3 tabulated files 'dataMatrix.tsv', sampleMetadata.tsv', and 'variableMetadata.tsv'

### Description

Note that the `dataMatrix` is transposed before export (e.g., the samples are written column wise in the 'dataMatrix.tsv' exported file).

### Usage

    writeEset(x, dirName, overwrite = FALSE, verbose = TRUE)

    ## S4 method for signature 'ExpressionSet'
    writeEset(x, dirName, overwrite = FALSE, verbose = TRUE)

### Arguments

`x` | An S4 object of class `ExpressionSet`
`dirName` | Character: directory where the tables should be written
`overwrite` | Logical: should existing files be overwritten?
`verbose` | Logical: should messages be printed?

### Value

No object returned.

### Examples

    library(ptairData)
    dirRaw <- system.file("extdata/exhaledAir", package = "ptairData")
    exhaledPtrset <- createPtrSet(dir=dirRaw, setName="exhaledPtrset",
    mzCalibRef = c(21.022, 60.0525), fracMaxTIC = 0.7, saveDir = NULL )
    exhaledPtrset<-detectPeak(exhaledPtrset,mz=c(21,59,77))
    eset <- ptairMS::alignSamples(exhaledPtrset )
    writeEset(eset, dirName = file.path(getwd(), "processed_dataset"))
    unlink(file.path(getwd(), "processed_dataset"),recursive = TRUE)
