Prepare activity (time-of-day) data for REST — ct_rest_activity • ct

Keeps independent detections of each species and converts their time of day to radians for circular activity modelling.

Usage

ct_rest_activity(
  detection_data,
  station_column = "Station",
  species_column = "Species",
  datetime_column = "DateTime",
  independence_minutes = 30
)

Arguments

detection_data: A data frame with one row per detection.
station_column, datetime_column: Columns for the station ID and datetime in detection_data.
species_column: Column for species in detection_data.
independence_minutes: Minimum gap (minutes) between successive detections at a station for them to count as independent.

Value

A tibble with columns Species, Station, time (radians).

Examples

data(rest_detection)

activity <- ct_rest_activity(rest_detection, independence_minutes = 30)
head(activity)
