Plot model biomass from a retrospective analysis

Usage

plot_retro(
  retro_fit,
  var = "total.biomass",
  by_stock = TRUE,
  min_catch_length = NULL,
  base_size = 8,
  ncol = NULL
)

retro_fit: A list of g3_fit objects that differ in their terminal year, i.e. the result of a retrospective analysis. The first object should have no years removed and the objects should be sorted chronologically with increasing number of years removed.
var: Character argument defining the variable to plot. Only "total.biomass" and "hr" are currently implemented.
by_stock: Logical indicating whether to produce plots by stock in addition to total biomass.
min_catch_length: Numeric value defining the minimum catch length (size), which will be used to filter (>=) the model population before calculating harvest rates using catches. Combines all stocks. Turn of by setting to NULL (default). Set to 0 to get HR for the entire model population. See Details.
base_size: Base size parameter for ggplot. See ggtheme.
ncol: Number of columns to be used in the plot.

A ggplot object.
