# swfscDAS 0.6.4

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

* remove [superseded](https://tidyselect.r-lib.org/news/index.html#lifecycle-changes-1-2-0) `.data$` syntax in tidyselect expressions

* Add OffSetGMT column to `das_effort` 'segdata' output (#12)


# swfscDAS 0.6.3

* 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


# swfscDAS 0.6.2

* 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)


# swfscDAS 0.6.1

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

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


# swfscDAS 0.6.0

* Fix `das_check` index math error (#5)

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


# swfscDAS 0.5.1

* Link fixes - no functionality changes

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


# swfscDAS 0.5.0 

* 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


# swfscDAS 0.4.0

* 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


# swfscDAS 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.


# swfscDAS 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


# swfscDAS 0.1.0

* Initial version, presented to NMFS users
