R Documentation

Productivity plot

Description

This uses the smoothed spawner estimates and smoothed fracwild estimates to compute a productivity metric. Type 3: wild(t+1)/wild(t). Type 1: wild(t+lag)/total(t), where wild is smoothed total estimate times smoothed fracwild estimate and total is the smoothed total estimate.

In the Viability Report, type=1 and the lag is set to 3 or 4 (depending on species).

Usage

productivity_plot(
  esu,
  pops,
  total.fit,
  fracwild.fit,
  min.year = NULL,
  max.year = NULL,
  type = 1,
  lag = 4,
  nwctrends.options = NULL
)

Arguments

`esu`	The name of the ESU
`pops`	The population names that will be plotted.
`total.fit`	total fit returned by `trend_fits()`
`fracwild.fit`	fracwild fit returned by `trend_fits()`
`min.year`	The x axis minimum. First year for numerator.
`max.year`	The x axis maximum. Last year for numerator.
`type`	The type of plot. Type 3: wild(t+1)/wild(t). Type 1: wild(t+lag)/total(t)
`lag`	The number of years prior to use in the denominator, e.g. spawnwers(year-lag). Note not used if type=3.
`nwctrends.options`	A list of plot options to change the appearance (colors, line types, line widths, point types, etc) in the plots. See `nwctrends.options` for a description of the options. Note, if `risk_plot_multipanel()` is called from `NWCTrends_report()` then `nwctrends.options` has already been set and can be left at `NULL` in this call.
