ARTFISH Fishing Unit - Shiny Server Module

Source: R/artfish_shiny_fishing_unit.R
artfish_shiny_fishing_unit_server.Rd

Server-side logic for the ARTFISH Fishing Unit dashboard.

The *"Catch and effort - Detailed by fishing unit"* module provides a dedicated workspace for exploring key output metrics derived from artfish_compute_report, with a focus on one or multiple fishing units. It enables users to analyse the evolution of fishing activity over time, with filtering options for fishing units and time range.

The module is composed of:

  • A selector panel to adjust the time range and fishing units to display

  • A set of KPIs presenting aggregated metrics for the selected period

  • Three boxed plots powered by fdishinyr::generic_chart allowing users to analyse ranked top items for:

    • (1) Species composition (by quantity)

    • (2) Fishing unit composition (by quantity)

    • (3) Fishing unit composition (by value)

  • Six boxed plots powered by fdishinyr::generic_chart allowing users to analyse key Artfish metrics:

    • (1) Total catch estimation

    • (2) Catch per unit effort (CPUE)

    • (3) Total nominal effort

    • (4) Activity coefficient

    • (5) Number of active vessels

    • (6) Total value estimation

Usage

artfish_shiny_fishing_unit_server(
  id,
  lang = NULL,
  estimate,
  effort_source,
  minor_strata = NULL
)

Arguments

id

Character string. Module namespace identifier.

lang

Optional language parameter. Can be either:

  • a character string (static language), or

  • a reactive returning a character string (dynamic language)

If NULL, the current global language is used. Default is NULL

estimate

effort_source

Reactive haracter string indicating the type of effort source. Must be either "fisher_interview" or "boat_counting".

minor_strata

Reactive haracter string targeting a column name considered as minor strata. Not activated
