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
