In DAPAR: Tools for the Differential Analysis of Proteins Abundance with R

Description

This function creates a column for the protein dataset after agregation by using the previous peptide dataset. It is a parallel version of the function BuildColumnToProteinDataset

Usage

BuildColumnToProteinDataset_par(peptideData, matAdj, columnName, proteinNames)

Arguments

peptideData	A data.frame of meta data of peptides. It is the fData of the MSnset object.
matAdj	The adjacency matrix used to agregate the peptides data.
columnName	The name of the column in fData(peptides_MSnset) that the user wants to keep in the new protein data.frame.
proteinNames	The names of the protein in the new dataset (i.e. rownames)

Value

A vector
