aggregateMean {DAPAR} | R Documentation

## Compute the intensity of proteins as the mean of the intensities of their peptides.

### Description

This function computes the intensity of proteins as the mean of the intensities of their peptides.

### Usage

    aggregateMean(obj.pep, X)

### Arguments

`obj.pep` | A peptide object of class `MSnset`
`X` | An adjacency matrix in which lines and columns correspond respectively to peptides and proteins.

### Value

A matrix of intensities of proteins

### Examples

    utils::data(Exp1_R25_pept, package='DAPARdata')
    obj.pep <- Exp1_R25_pept[1:10]
    obj.pep.imp <- wrapper.impute.detQuant(obj.pep, na.type='missing')
    protID <- obj.pep@experimentData@other$proteinId
    X <- BuildAdjacencyMatrix(obj.pep.imp, protID, FALSE)
    ll.agg <- aggregateMean(obj.pep.imp, X)
