Selects biomolecules for normalization via choosing all biomolecules currently in the data
all_subset(e_data, edata_id)a \(p \times n + 1\) data.frame, where \(p\) is the number of peptides, proteins, lipids, or metabolites and \(n\) is the number of samples. Each row corresponds to data for a peptide, protein, lipid, or metabolite, with one column giving the biomolecule identifier name.
character string indicating the name of the peptide, protein,
lipid, or metabolite identifier. Usually obtained by calling
attr(omicsData, "cnames")$edata_cname.
Character vector containing all biomolecules.
This function returns the subset of all biomolecules. These will be used for normalization.
