summarizeIntensities {qPLEXanalyzer} | R Documentation

## Summarizes peptides intensities to proteins

### Description

Summarizes multiple peptides intensities measurements to protein level.

### Usage

    summarizeIntensities(MSnSetObj, summarizationFunction, annotation)

### Arguments

`MSnSetObj` | MSnSet; an object of class MSnSet
`summarizationFunction` | function; method used to aggregate the peptides into proteins. Sum, mean or median
`annotation` | data.frame; a data.frame of protein annotation of four columns: "Accessions", "Gene", "Description" and "GeneSymbol"

### Value

An object of class `MSnSet` (see `MSnSet-class`)

### Examples

    data(human_anno)
    data(exp3_OHT_ESR1)
    MSnSet_data <- convertToMSnset(exp3_OHT_ESR1$intensities_qPLEX1,
                                   metadata=exp3_OHT_ESR1$metadata_qPLEX1,
                                   indExpData=c(7:16),
                                   Sequences=2,
                                   Accessions=6)
    MSnset_P <- summarizeIntensities(MSnSet_data, sum, human_anno)
