Counts the analytes across the different injections — count

This functions counts the number of different peakgroups, peptides and proteins in different injections.

count_analytes(
  data,
  column_levels = c("transition_group_id", "FullPeptideName", "ProteinName"),
  column_by = "run_id",
  rm_decoy = TRUE
)

Arguments

data: A data frame containing SWATH data.
column_levels: Columns in which the number of unique identifiers should be counted.
column_by: Column for which the different identifiers should be counted for, e.g. for the different injections.
rm_decoy: Option to not remove decoy before counting.

Value

Returns a data frame with the count of the different identifiers per e.g. injection.
