Combine different peptide variants into a single intensity — summarize_peptide

Peptide intensities can be split out over different entries based on different charge states or modifications. This function combines these variants into one intensity per peptide sequence.

Usage

summarize_peptide_intensities(pr_matrix, peptide_level = "Stripped.Sequence")

Arguments

pr_matrix: The report.pr_matrix file
peptide_level: The column in pr_matrix that is used to aggregate.

Value

a matrix with a single peptide intensity per sample for each entry in the peptide_level column

Examples


mat <- summarize_peptide_intensities(report.pr_matrix)
