ct_get_effort: Calculate camera trap deployment effort

In ct: Camera Trap Data Management and Multi-Method Ecological Analysis

Calculate camera trap deployment effort

Description

Computes the monitoring effort (e.g., in days) for each camera deployment based on start and end timestamps.

Usage

ct_get_effort(
  deployment_data,
  start_column,
  end_column,
  deployment_column,
  format = "%Y-%m-%d %H:%M:%OS",
  time_zone = "",
  time_unit = "days"
)

Arguments

deployment_data	A data frame containing camera trap deployment records.
start_column	The column name (unquoted or as a string) indicating deployment start datetime.
end_column	The column name (unquoted or as a string) indicating deployment end datetime.
deployment_column	The column name (unquoted or as a string) that uniquely identifies the deployment (e.g., camera ID).
format	A character string specifying the format of the datetime columns. Default is "%Y-%m-%d %H:%M:%OS".
time_zone	The time zone used to parse the datetime columns. Default is "" (i.e., system time zone).
time_unit	The unit in which to compute the effort duration. Can be "secs", "mins", "hours", "days", or "weeks". Default is "days".

Value

A data frame with columns:

• deployment_column: Deployment identifier

• effort: Numeric value of monitoring effort

• effort_unit: The time unit used
