Raw

isoreader 1.4.0

Breaking changes

Several previously deprecated functions have been removed: iso_calculate_ratios(), iso_convert_signals(), iso_convert_time(), iso_plot_continuous_flow_data(), iso_plot_dual_inlet_data(), iso_plot_raw_data(), isoread(). Older code that still uses these functions instead of their replacements will no longer work.

New features

  • simpler cache file names that also removed dependency on the UNF package
  • faster implementation of binary file structure analysis for isodat files, accessible via the new iso_get_source_file_structure() function

Enhancements

  • ~20% performance increase in reading isodat files through code optimization
  • iso_export_to_excel() and iso_export_to_feather() renamed to iso_export_files_to_excel() and iso_export_files_to_feather(), respectively, to avoid ambiguity with other export functions.

Bug fixes

  • fixes to be compatible with latest tidyselect and dplyr updates

isoreader 1.3.0

Major changes

  • functions for previously deprecated .rda file format removed
  • R version (>= 4.0.0) and dependency version requirements clarified
  • dependencies simplified (openxlsx, feather, xml2 and rhdf5 are now optional extensions)

Bug fixes

  • dependency on pandoc removed

isoreader 1.2.3

Major Features

Reading isotope ratio mass spectrometry (IRMS) data files

This package currently supports reading the following raw data files:

  • continuous flow data files from mass spectrometers run by Isodat and IonOS software (?iso_read_continuous_flow)
  • dual inlet data files from mass spectrometers run by Isodat and Nu software (?iso_read_dual_inlet)
  • scan data files from mass spectrometers run by Isodat software (?iso_read_scan)

Aggregating data from files

This package provides the following data aggregation and data processing functionality for all supported data files:

  • aggregating file information including sequence line data (?iso_get_file_info)
  • aggregating raw mass spectrometric data (?iso_get_raw_data)
  • aggregating mass spectrometric background data (?iso_get_bgrd_data)
  • aggregating vendor-specific data tables if provided in raw file formats (?iso_get_vendor_data_table)
  • aggregating information on detector resistors if included in raw file formats (?iso_get_resistors)
  • aggregating information on internal isotope standards if included in raw file formats (?iso_get_standards)
  • processing file information with tidyverse-equivalent select, rename, mutate and filter functions (?iso_filter_files, ?iso_select_file_info, ?iso_rename_file_info, ?iso_mutate_file_info)
  • adding file information with ?iso_add_file_infoto simplify sequential join operations

Exporting information

This package provides the following data export functionality for all supported data files:

  • export to open Excel (.xslx) with ?iso_export_files_to_excel
  • export to the Python/R cross-over feather file format with ?iso_export_files_to_feather
