xxx

Usage

select_topn(pepData, X, n = 10, funpept = "Mean")

Arguments

pepData

A matrix containing the peptide intensities.

X

A matrix acting as an adjacency matrix.

n

A numeric(1) specifying the number of peptides to use for each protein.

funpept

A function used for determining a peptide's value. Available functions are Sum, Mean or Median.

Value
