calculateIsotopeRatio: Ratio calculation

In pulsedSilac: Analysis of pulsed-SILAC quantitative proteomics data

Description

Calculates the ratio between the new isotope and the old isotope (new/old).

Usage

calculateIsotopeRatio(x, newIsotopeAssay, oldIsotopeAssay, ...)

## S4 method for signature 'SilacProteinExperiment'
calculateIsotopeRatio(x, newIsotopeAssay, oldIsotopeAssay)

## S4 method for signature 'SilacPeptideExperiment'
calculateIsotopeRatio(x, newIsotopeAssay, oldIsotopeAssay)

## S4 method for signature 'SilacProteomicsExperiment'
calculateIsotopeRatio(x, newIsotopeAssay, oldIsotopeAssay)

Arguments

x	A SilacProteinExperiment, SilacPeptideExperiment or a SilacProteomicsExperiment object.
newIsotopeAssay	A character indicating the assay name that has the new isotope intensity data.
oldIsotopeAssay	A character indicating the assay name that has the old isotope intensity data.
...	Unused.

Value

A SilacProteinExperiment, SilacPeptideExperiment or a SilacProteomicsExperiment object with an added assay named 'ratio'.

Examples

data('wormsPE')
calculateIsotopeRatio(x = wormsPE,
                      newIsotopeAssay = 'int_heavy',
                      oldIsotopeAssay = 'int_light')
