clean_stock_trends: Clean stock status trends

In ices-tools-prod/fisheryO: Fisheries Overviews for ICES Advice

Description

clean_stock_trends returns list of 2: data frame of F and SSB relative to F_MSY and MSY B_trigger reference points for stocks of a fish category for an ecoregion and sag_complete_summary from clean_sag.

Usage

clean_stock_trends(active_year = 2016, grouping_var = c("EcoGuild",
  "EcoRegion", "FisheriesGuild")[1], plotting_var = c("StockCode",
  "FisheriesGuild")[1], metric = c("MSY", "MEAN")[1])

Arguments

active_year	numeric of the stock database version (year). e.g., 2016
grouping_var	character string of the desired grouping. Options include: EcoRegion, EcoGuild, or FisheriesGuild
plotting_var	character string of the variable to plot. Options include: StockCode or FisheriesGuild (mean)
metric	character string of the desired metric. Options include: MSY or MEAN (according to grouping_var)

Value

A list of 2: 1) data frame of F and SSB relative to F_MSY and MSY B_trigger reference points for stocks of a fish category for an ecoregion and 2) sag_complete_summary from clean_sag.

Note

Stocks are linked to ecoregions and fish categories via the ICES Stock database. Reference points are as published in ICES Stock Assessment Graphs database. In some cases, status relative to reference points may vary from published ICES advice when reported F or SSB are very close to reference points (e.g., F = 0.201 > F_MSY = 0.20).
