SumPeptides {DAPAR} | R Documentation

## Compute the intensity of proteins with the sum of the intensities of their peptides.

### Description

This function computes the intensity of proteins based on the sum of the intensities of their peptides.

### Usage

    SumPeptides(matAdj, expr)

### Arguments

`matAdj` | An adjacency matrix in which lines and columns correspond respectively to peptides and proteins.
`expr` | A matrix of intensities of peptides

### Value

A matrix of intensities of proteins

### Examples

    require(DAPARdata)
    data(Exp1_R25_pept)
    protID <- "Protein.group.IDs"
    M <- BuildAdjacencyMatrix(Exp1_R25_pept[1:1000], protID, FALSE)
    SumPeptides(M, Biobase::exprs(Exp1_R25_pept[1:1000]))
