add_n_pepexpzR Documentation

Calculates the number of unique charge states of peptides.

Description

Calculates the number of unique charge states of peptides.

Usage

add_n_pepexpz(df, group_psm_by = "pep_seq", use_unique = TRUE)

Arguments

df

A data frame.

group_psm_by

A character string specifying the method in PSM grouping. At the pep_seq default, descriptive statistics will be calculated based on the same pep_seq groups. At the pep_seq_mod alternative, peptides with different variable modifications will be treated as different species and descriptive statistics will be calculated based on the same pep_seq_mod groups.

use_unique

Logical; if TRUE, filter data by uniqueness.
