Rtrack 2.0.4

• Improved skew correction of square arenas (OFT and NOR).
• NOR objects may now be arbitrary shapes.
• Implemented ‘raw.free.xxx’ track file formats, which enable flexible customisation for reading in data from unsupported sources.
• Improved variable plots with options for parametric and non-parametric data.
• Fixed many edge cases in the variable plots.
• Changed the calculation of ‘holes.before.goal’ in the Barnes maze to make it more robust.
• Fixed a tricksy bug that made reading an experiment from a URL sometimes not work.
• Added a patch to allow legacy Rtrack JSON archives to be read in the new system.
• Added checks to disallow experiments with mixed arena types.
• Improved customisation of all plots.
• Improved aesthetics of path and density plots.

Rtrack 2.0.3

• Fixes for several Windows-specific bugs.
• Codebase is now routinely tested on MacOS (Apple Silicon and Intel), Ubuntu Linux and Windows 10.
• Fixed bug where custom series colours in the variable plots could be incorrectly ordered.
• Fixed bug where APA zones at certain angles were incorrectly processed.
• Added ability to rotate MWM and Barnes maze arenas to allow alignment.
• Improved support for Topscan 3.0 track files.

Rtrack 2.0.2

• Major update including support for multiple experiment types.
• Code rewrite to remove dependency on the discontinued sp package.
• Changed arena definitions to require time units.
• New metrics added and exposed to the user a bit differently to be more compatible across the different experiment types.
• MWM strategy caller updated to incorporate the other changes in this release.
• Strategy caller for the Barnes maze added.
• Added support for the new trackxf archive format.

Rtrack 1.0.7

• Added support for additional input formats.
• Code update to reflect changing dependencies.
• Fixed bug when plotting strategies with user-defined trial boundaries.
• Fixed export to JSON when no experimental factors are present.

Rtrack 1.0.1

• Added a function to conveniently subset the experiment object.
• It is now possible to plot x-axis ticks in strategy and variable plots either by Day or by Trial.
• Added the ability to suppress titles and x-axis ticks to the strategy and variable plots to enable further customisation.
• The strategy plot now returns cumulative strategy use data to allow custom plots to be built.

Rtrack 1.0.0

• Fixed the case where plots failed if only one arena was used.
• Added a missing variable in the summary output.

Rtrack 0.9.10

• Ability to trim track files during reading added.
• Catches case where plotting strategies in the absence of arena boundaries failed.

Rtrack 0.9.7

• Path interpolation now implemented.
• Bug preventing reading experiment descriptions from CSV or tab-delimited files fixed.
• check_experiment now aware of all supported track formats.
• identify_track_format now returns supported formats when called with NULL argument.
• Determining format of plain text files now works properly.
• read_path now returns a valid rtrack_path object of zero path length for empty tracks.
• calculate_metrics checks for zero-length paths and skips them (returning NULL) to avoid disrupting batch processing.
• Legend placement in variable plots improved.
• Catches cases where path no initial trajectory can be calculated.
• Web links updated to point to new SSL-secured (https) site.

Rtrack 0.9.6

• Added listing of supported formats when identify_track_format() is called with NULL argument.
• Added support for header-free text files.
• Bug fixed in ensuring no perseverance in absence of old goal.
• Catches cases where path is of zero length (no tracking data was recorded). read_path() now fails with a warning in such cases.

Rtrack 0.9.3

• Version initially released to CRAN.
