Aggregates the isotopic standard information recovered from the provided iso_files. Can aggregate just the standards' delta values or combine the delta values with the recovered ratios (if any). Use parameter select to exclude/include the ratios. All standards info is only available if the iso_files were read with parameter read_method_info=TRUE.

iso_get_standards(
  iso_files,
  select = everything(),
  include_file_info = NULL,
  with_ratios = NULL,
  quiet = default(quiet)
)
