groupMemberPeptides {isobar} | R Documentation |
For a given reporter protein group identifier, information on its peptides is returned. It contains information on how the peptides are shared and in which member they occur.
groupMemberPeptides(x, reporter.protein.g, ordered.by.pos = TRUE, only.first.pos = TRUE)
x |
ProteinGroup object |
reporter.protein.g |
group reporter protein |
ordered.by.pos |
if TRUE, start position of peptides in proteins is exported and peptides are ordered by position |
only.first.pos |
if TRUE, only first occurence of peptide in protein is reported |
list of two: [1] peptide.info: data.frame peptide specificity n.shared.groups n.shared.proteins start.pos [2] group.member.peptides: data.frame each column corresponds to a group member, and each row to a peptide
