Sometimes it is useful to reload isotope files from their original data files (e.g. after modifying raw data files in vendor software, or after upgrading to a newer version of the isoreader package that provides new functionality). The functions described below are intended to make this very easy. However, re-reading files from disc is only possible if file paths still point to the original raw data files. If they have moved, please use iso_set_file_root first to change the root directory of your iso_files.

iso_reread_files(iso_files, ...)

iso_reread_all_files(
  iso_files,
  ...,
  stop_if_missing = FALSE,
  quiet = default(quiet)
)

iso_reread_changed_files(
  iso_files,
  ...,
  stop_if_missing = FALSE,
  quiet = default(quiet)
)

iso_reread_outdated_files(
  iso_files,
  ...,
  stop_if_missing = FALSE,
  quiet = default(quiet)
)

iso_reread_problem_files(
  iso_files,
  ...,
  stop_if_missing = FALSE,
  reread_files_with_errors = TRUE,
  reread_files_with_warnings = FALSE,
  quiet = default(quiet)
)

iso_reread_storage(...)

iso_reread_archive(...)

Arguments

iso_files

collection of iso_files

...

additional read parameters that should be used for re-reading the iso_files, see iso_read_dual_inlet, iso_read_continuous_flow and iso_read_scan for details (except read_cache which is always set to FALSE to force re-reads).

stop_if_missing

whether to stop re-reading if any of the original data files are missing (if FALSE, will warn about the missing files adding a warning to them, but also re-read those that do exist)

quiet

whether to display (quiet=FALSE) or silence (quiet = TRUE) information messages. Set parameter to overwrite global defaults for this function or set global defaults with calls to iso_turn_info_messages_on and iso_turn_info_messages_off

reread_files_with_errors

whether to re-read files that had read in with errors the last time (default TRUE)

reread_files_with_warnings

whether to re-read files that had read in with warnings the last time (default TRUE)

Details

To re-read files that have been modified on disc, please use iso_reread_changed_files(). To re-read files because of an isoreader version upgrade, please use iso_reread_outdated_files(). To try re-reading files that previously had warnings and/or errors, please use iso_reread_problem_files().

iso_reread_all_files re-reads all files in the collection.

iso_reread_changed_files re-reads all files that have been modified (e.g. in the vendor software) since they were last read by isoreader.

iso_reread_outdated_files re-reads all files that were read with an outdated version of isoreader.

iso_reread_problem_files re-reads all files that have had errors the last time they were read by isoreader (set reread_files_with_warnings = TRUE to also re-read those that have warnings).

iso_reread_storage is deprecated.

iso_reread_archive is deprecated.
