Calculates a range of metrics from path coordinates.
calculate_metrics(path, arena)An rtrack_metrics object containing metrics of the search path.
This object is required as input for the call_strategy and
plot_path functions.
An rtrack_path object as returned by
read_path.
An rtrack_arena object as returned by
read_arena.
Metrics are calculated based on normalised coordinate data and are available
as the summary element of the rtrack_path object. Unnormalised
values (with the same units as the raw data) are also available as the
unscaled.summary element. These can be useful for custom plots and are
also the values exported by export_results. Extended metrics
are available as separate elements of the rtrack_path object.
read_path, read_arena, and also
read_experiment for processing many tracks at once.
