aggregateTopn {DAPAR} | R Documentation

## Compute the intensity of proteins as the sum of the intensities of their n best peptides.

### Description

This function computes the intensity of proteins as the sum of the intensities of their n best peptides.

### Usage

    aggregateTopn(obj.pep, X, method = "Mean", n = 10)

### Arguments

`obj.pep` | A matrix of intensities of peptides
`X` | An adjacency matrix in which lines and columns correspond respectively to peptides and proteins.
`method` | xxx
`n` | The maximum number of peptides used to aggregate a protein.

### Value

A matrix of intensities of proteins

### Examples

    require(DAPARdata)
    data(Exp1_R25_pept)
    obj.pep <- Exp1_R25_pept[1:1000]
    protID <- "Protein.group.IDs"
    X <- BuildAdjacencyMatrix(obj.pep, protID, FALSE)
