Example camera timestamps dataset (ingress-egress mode)

A dataset of raw ingress and egress timestamps recorded by a remote camera at a boat launch. Contains 14 rows spanning 4 sampling days in June 2024 (3-4 anglers per day). Suitable for use with preprocess_camera_timestamps. One row has a trip duration greater than 8 hours (an unusually long fishing day); all other durations are between 1.5 and 5.5 hours.

Usage

example_camera_timestamps

Format

A data frame with 14 rows and 4 variables:

date

Survey date (Date class), June 2024.

day_type

Day type stratum: "weekday" or "weekend".

ingress_time

Angler arrival time (POSIXct, America/Chicago timezone).

egress_time

Angler departure time (POSIXct, America/Chicago timezone). Always later than ingress_time.
