Normalize fishing effort to angler-hours

Source: R/creel-design.R
compute_angler_effort.Rd

Multiplies per-trip effort (hours) by party size (number of anglers) to produce angler-hours. This converts party-level effort records to individual-angler units, which are required for CPUE and harvest-rate computations.

This function can be called standalone on a raw data frame or is called internally by add_interviews when constructing the design object.

Usage

compute_angler_effort(data, effort, n_anglers)

Arguments

data

A data frame containing the interview records.

effort

Tidy selector for the effort column (numeric, hours per trip).

n_anglers

Tidy selector for the number-of-anglers column (positive integer).

Value

The input data frame with an added .angler_effort column (numeric, angler-hours). Existing columns are preserved.
