Description

Helper of calc_pep_retsd

Usage

add_pep_retsd(
  df,
  group_psm_by = "pep_seq_mod",
  use_unique = TRUE,
  col_rt = "pep_apex_ret"
)

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.
col_rt	The column key of retention time.
