Creating a list of matrices of fragment ion intensities for all proteins

Description

For each protein, a numerical matrix is formed where the columns are samples and rows are fragment ions.

Usage

create_protein_list(preprocessed_data)

Arguments

preprocessed_data

A data frame of four components as output of the preprocess function.

Value

A list where each element contains the quantitative data of a protein. The column names are sample names and the row names fragment ions.
