getSamples: Get Sample Names From metabCombiner or metabData Object

In hhabra/Combiner: Method for Combining LC-MS Metabolomics Feature Measurements

Get Sample Names From metabCombiner or metabData Object

Description

Returns the sample names from one of the two datasets used in metabCombiner analysis, denoted as 'x' or 'y.'

Usage

getSamples(object, data = NULL)

## S4 method for signature 'metabCombiner'
getSamples(object, data = NULL)

## S4 method for signature 'metabData'
getSamples(object)

Arguments

object	metabCombiner or metabData object
data	dataset identifier for metabCombiner objects

Value

character vector of sample names. For metabCombiner objects these may come from the 'x' dataset (if data = "x") or the 'y' dataset (if data = "y").

Examples

data(plasma30)
data(plasma20)

p30 <- metabData(plasma30, samples = "CHEAR")
p20 <- metabData(plasma20, samples = "Red", rtmax = 17.25)

p.comb <- metabCombiner(xdata = p30, ydata = p20)

getSamples(p30)
getSamples(p.comb, data = "x")  #equivalent to previous
getSamples(p20)
getSamples(p.comb, data = "y")  #equivalent to previous
