stecf_plot: STECF Landings over time by country, guild, or species

In slarge/fisheryO: Fisheries Overviews for ICES Advice

Description

The stecf_plot function returns an area or line plot of landings (historic and official catch) for an ecoregion by country guild, or species.

Usage

stecf_plot(ecoregion, metric = c("EFFORT", "LANDINGS")[1], type = c("GEAR",
  "COUNTRY")[1], line_count = 4, plot_type = c("line", "area")[1],
  data_caption = TRUE, file_name = NULL, save_plot = FALSE,
  output_path = NULL, return_plot = TRUE, return_data = FALSE,
  fig.width = 174, fig.height = 68, text.size = 9, ...)

Arguments

ecoregion	ecoregion name, e.g. Greater North Sea Ecoregion
metric	the value to plot e.g., EFFORT or LANDINGS
type	the variable that will be used to group and display data: COMMON_NAME, GUILD, or COUNTRY
line_count	number of lines to display
plot_type	area or line plot
data_caption	print the data source as a caption, boolean.
file_name	name for the output.
save_plot	logical to save plot.
output_path	path for output to live.
return_plot	logical to return plot to current environment.
return_data	logical on returning a .csv of plotted data
fig.width	width pf combined set of plots
fig.height	height of combined set of plots
text.size	= size of text in plots

Value

A ggplot2 object when return_plot is TRUE or .png when save_plot is TRUE. Output is saved as file_name in output_path. When file_name is NULL, the file name is the ecoregion. When output_path is NULL, the file is saved to "~/".

Note

Some considerable errors have been identified in the STECF data. Finland and Estonia effort data are not reliable, and Germany recorded an erroneous haul in 2013. These values have been removed.
