Usage

SumPeptidesSpeedUp(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

Run this code
data(UPSpep25)
protID <- "Protein.group.IDs"
M <- BuildSparseAdjacencyMatrix(UPSpep25, protID, FALSE)
SumPeptidesSpeedUp(M, Biobase::exprs(UPSpep25))
