Fetch peak mappings that were problematic in any way. This function is typically called after iso_map_peaks to inspect problematic entries. Use the select parameter to select only the most informative columns (always includes at minimum the peak_info and problem columns to identify why the peak is problematic). Note that peaks that are ambiguous because of multiple potential map matches have a data table entry for each potential match.

iso_get_problematic_peak_mappings(dt, select = everything(),
  unidentified = TRUE, missing = TRUE, ambiguous = TRUE,
  quiet = default(quiet))

Arguments

dt

data table with mapped peaks. Requires the is_identified, is_missing and is_ambiguous columns to be present.

select

which column to select, by default all

unidentified

whether to include peaks that are problematics because they are unidentified

missing

whether to include peaks that are problematics because they are missing

ambiguous

whether to include peaks that are problematics because they are ambiguously identified

quiet

whether to display (quiet=FALSE) or silence (quiet = TRUE) information messages.

Value

data table with rows for problematic peaks and the select-identified columns
