groupMemberPeptides {isobar} | R Documentation

## Peptide info for protein group members

### Description

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.

### Usage

    groupMemberPeptides(x, reporter.protein.g, ordered.by.pos = TRUE, only.first.pos = TRUE)

### Arguments

`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

### Value

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

### Examples

        data(ibspiked_set1)
        protein.group <- proteinGroup(ibspiked_set1)
        ceru.rat <- protein.g(protein.group,"CERU_RAT")
        groupMemberPeptides(protein.group,ceru.rat)

    ## find protein groups with members
        t <- table(proteinGroupTable(protein.group)$reporter.protein)
        t[t>2]
        protein.g <- names(t)[t>2][1]
        groupMemberPeptides(protein.group,protein.g)
