In seananderson/catchstatus: Methods to assign status to fish stocks based on catch series.

Description

Takes the status of a group of fisheries through time and plots them in a stacked polygon layout. Data can be pre-aggregated by year or in long format (e.g. a column for stock ID, a column for year, and a column for status). The function will aggregate by year.

Usage

plot_status_stacked(year,
status,
xlab = "Year",
ylab = "Percentage of stocks",
mask_last_year = TRUE,
xlim = NULL,
...)

Arguments

year	The years to plot.
status	The status. Should be a factor with levels of 1:6 representing: "Undeveloped", "Developing", "Rebuilding", "Fully exploited", "Overexploited", and "Collapsed", in that order.
xlab	The x-axis label.
ylab	The y-axis label.
mask_last_year	Should the last year be plotted?
xlim	The x-axis limits. Defaults to the range of years given.
...	Other parameter values to pass to plot.default().
