plotLBB: Plotting LBB fit

In polehalieutique/demerstem: This package aims to falicitate Fish stock assessement for west african partners involved in the EU DEMERSTEM project

Plotting LBB fit

Description

Function to plot data and fit of a LBB assessment

Usage

plotLBB(
  lfq,
  GausSel = FALSE,
  LcUser = NA,
  mmUser = FALSE,
  MKUser = NA,
  LstartUser = NA
)

Arguments

lfq	A list of the class "lfq" consisting of following parameters: species species name, stock stock ID or name, midLengths midpoints of the length classes, dates dates of sampling times (class Date), catch matrix with catches/counts per length class (row) and sampling date (column), comments comments;
GausSel	Logical; indicating the selectivity pattern. If FALSE (default) trawl-like, if TRUE gaussian selectivity is assumed.
LcUser	Optional, user defined selectivity parameter. If NA (default) L10 and L90 are used to estimate a proxy for Lc.
mmUser	Logical; indicating the unit of length measurements, where TRUE indicates that lengths are in mm and FALSE (default) indicate that lengths are in cm.
MKUser	Optional; user defined MK ratio. If NA (default) MK ratio is set to 1.5.
LstartUser	Optional, user defined length at which selectivity is 0.95. If NA (default) Lstart (L95) is estimated by the model.

Details

Plot aggregated histogram with fit to fully selected part.
