Plot sampled length structure against target simulated size composition

A function that plots the observed size structure against the expected size composition at the target SPR

plotTarg(LB_pars = NULL, LB_lengths = NULL, yr = 1, Cols = NULL,
  title = NULL, targtext = TRUE, size.axtex = 12, size.title = 14,
  scales = c("fixed", "free_x", "free_y", "free"))

Arguments

LB_pars	an object of class 'LB_pars' that contains the life history and fishing information
LB_lengths	an object of class 'LB_lengths' that contains the observed size data
yr	index for sampled length data (defaults to 1)
Cols	optional character vector of colours for the plot
title	character - optional title for plot
targtext	logical - should the SPR target text be displayed as a subtitle?
size.axtex	size of the axis text
size.title	size of axis title
scales	argument to ggplot2 function. Are scales shared across all facets (the default, "fixed"), or do they vary across rows ("free_x"), columns ("free_y"), or both rows and columns ("free")

Value

a ggplot object
