extract_annotation: Protein annotation extraction

Description

Extracts annotation columns from a long-format input

Usage

extract_annotation(protein_ids, quant_table, primary_id = "PG.ProteinGroups",
                   annotation_columns = NULL)

Value

A table of proteins and associated annotation extracted from the input.

Arguments

protein_ids

A vector of protein ids.

quant_table

A long-format input table. The input is typically the same as input to the preprocess function.

primary_id
