                     Changes in version 0.7.0.9000                      

  - Fix bug in das_process of incorrect OffsetGMT values, stemming from
    as.Date using 'UTC' tz by default (#16)

  - Added an exported function das_spcodes_read for consistent reading
    of shipboard SpCode files

  - Changed the argument name in das_check of the user-provided SpCodes
    file from sp.codes to sp.codes.file. Also added a sp.codes.skip
    argument to pass to das_spcodes_read

  - Moved example data files to an 'extdata' folder within 'inst'

  - Update link to NOAA Tech Memo describing DAS data; now
    (https://repository.library.noaa.gov/view/noaa/3174)https://repository.library.noaa.gov/view/noaa/3174

  - Update roxygen to use markdown, fix documentation issues related to
    upgrade to roxygen2 v8.0

  - Added the SpCodes.dat file from CruzPlot to 'inst' to have available
    as a default

                 Changes in version 0.6.4 (2025-06-10)                  

  - The DateTime column in das_read output now has a timezone of ""
    (#13)

                 Changes in version 0.6.3 (2024-07-03)                  

  - Moved repo to https://github.com/SWFSC, and updated all associated
    documentation. Also generalized documentation to not be as
    SWFSC-focused, and thus speak to more general uses of DAS files

  - Generalized package title and description to not be SWFSC-specific

  - Changed license to Apache License (== 2), based on NMFS guidance at
    https://nmfs-opensci.github.io/GitHub-Guide

                 Changes in version 0.6.2 (2023-08-10)                  

  - Use reframe in grouping summaries in das_sight for when none of a
    certain event are in the data (#8)

  - Ensure that sum(GsSpx) equals GsSchoolx, for all of Best, High and
    Low (#9)

                 Changes in version 0.6.1 (2022-01-31)                  

  - Fix bug in das_sight and das_effort when the DAS file contains no
    sightings

  - Changed license based on https://github.com/NOAAGov

                 Changes in version 0.6.0 (2021-09-03)                  

  - Fix das_check index math error (#5)

  - Removed the tz argument from das_read, and added 'OffsetGMT' to the
    output of das_process

                 Changes in version 0.5.1 (2021-05-27)                  

  - Link fixes - no functionality changes

  - swfscDAS now depends on R >= 4.0.0 for consistency across package
    dependencies

                 Changes in version 0.5.0 (2021-01-07)                  

  - Added 'strata.files' argument to das_effort to allow users to split
    effort by strata

  - The 'segdata' output of das_effort now includes DateTime1 and
    DateTime2, the date/time of the start and end points of each
    segment. The column order of the segdata data frame was also
    slightly changed for consistency

  - Using the 'continuous' method of das_effort, effort can now also be
    chopped using 'Course' and 'SptKt'

  - Changed the name of the strata argument of das_intersects_strata to
    'strata.files' for consistency

  - Fixed a bug in das_check where multiple files could not be checked
    at once

  - das_check now checks for valid longitude and latitude values

  - Fixed an issue where the sample stratum file did not overlap with
    any of the sample data

  - Added documentation describing how das_sight handles additional
    sperm whale group size estimates

  - das_chop_condition, das_chop_equallength, das_chop_section, and
    das_segdata are now exported for documentation purposes only

                 Changes in version 0.4.0 (2020-06-30)                  

  - Changed das_within_strata to das_intersects_strata because it uses
    the geometric binary predicate st_intersects rather than st_within

  - In das_effort_sight, users can now use gs.columns to specify
    secondary group size columns in case of an NA group size value

                        Changes in version 0.3.0                        

  - das_process now lets the user add the DateTime, Lat, and Lon
    information to "?" and numeric (1:8) events using the
    'add.dtll.sight' argument. This enables the user to filter the
    processed DAS data by date/time or coordinates, if desired

  - For consistency with species code columns, the column name 'SpProb'
    is now 'SpCodeProb' in das_sight output

  - In das_sight, species-specific group sizes are now calculated as the
    mean of the product of the school estimate and the corresponding
    species percentage (for each estimate), rather than the product of
    the mean of the school estimate and the mean of the corresponding
    species percentage.

  - das_effort_sight now has an argument that lets the user use the low
    group size estimate in place of an NA best group size estimate

  - Changed das_chop_equal to das_chop_equallength for naming
    consistency. This change should not affect users, as it does not
    affect any of the syntax required when using das_effort

  - Added das_within_strata for checking if individual points, such as
    event points or segment midpoints, are within user-provided strata

  - The "DAS_data_join" vignette demonstrates how to join external data,
    such as from DAT files, to processed DAS data

  - Where applicable, error, warning, and informational messages now
    report both the file name and line number. This makes the messages
    more useful when working with concatenated DAS objects with multiple
    DAS files.

                        Changes in version 0.2.0                        

General

  - Added 'Data9', 'Data10', and 'Data12' columns to the output of
    das_read and das_process to account for all recorded sighting
    information. These data are now extracted as 'CalibSchool',
    'PhotosAerial', and 'Biopsy' from "S" events in das_sight, and
    checked in das_check

  - Added 'SpdKt' (ship speed in knots) and 'WindSpdKt' (wind speed in
    knots) to the output of das_process. The sources for these data are
    also checked in das_check

  - Renamed items in effort list output of das_effort and
    das_effort_sight: 'siteinfo' is now 'sightinfo', and segdata columns
    indicating the number of sightings or animals on a segment are now
    formatted as 'description'_'species code', e.g. "nSI_075"

das_sight changes

  - Fixed a bug when processing "G" and "g" events

  - Added columns for high and low (in addition to best) estimates of
    school size

  - Renamed columns to follow a consistent format - see das_sight
    documentation for a complete description of the various return
    format outputs

  - Added a "complete" return format, which has a row for every observer
    estimate for each sighting

  - Users can now use a das_sight argument to provide the event code(s)
    by which they wish to filter the function output

                        Changes in version 0.1.0                        

  - Initial version, presented to NMFS users
