Plot model length distributions for stocks by year

Usage

plot_ldist(
  fit,
  type = "line",
  by_age = FALSE,
  stocks = NULL,
  scales = "fixed",
  ncol = NULL,
  years = NULL,
  base_size = 8
)

Arguments

fit: A gadget fit object. See g3_fit.
type: Character specifying the plot type. Options: "line", "bar", or "ggridges".
by_age: Logical indicating whether the length distributions should be grouped by age. Works only with type = "line".
stocks: Character specifying the substock to plot in fit. If NULL, all stocks are plotted.
scales: Character defining the facet_wrap scales argument to use.
ncol: Number of columns passed to facet_wrap
years: Numeric vector defining which years to plot. If NULL (default), all years are plotted.
base_size: Base size parameter for ggplot. See ggtheme.

Value

A ggplot object or a list of such objects depending on the type argument.

Details

Do not trust the absolute numbers when by_age = TRUE. They are estimated from normal distributions by using number * dnorm(1:120, mean = mean_length, sd = stddev_length).

Examples

data(fit)
plot_ldist(fit)

plot_ldist(fit, type = "bar")

plot_ldist(fit, type = "ggridges")

plot_ldist(fit, by_age = TRUE, years = 2021)
