Fishing Area Country Analysis

This function analyzes the fishing area data and generates plots for specified country based on their ranking in terms of total tonnes.

Arguments

area_data: A data frame containing the fishing area data.
rank_range: The ranks of the countries to show, ranked by their catch (see rank_years): the ranks listed, e.g. 1:10 (default) for the first ten, c(5, 6) for the fifth and sixth, or c(1, 10) for the first and the tenth. Ranks beyond the number of countries are left out. Until version 0.9.0 two numbers gave the first and the last rank (c(1, 10) was the first ten).
rank_years: The number of recent years whose catch ranks the countries, e.g. 5 for the last five years (as in the tables of fao_report()). Default is NULL: the catch of all years. The charts show the whole series either way.
plot: A logical value indicating whether to generate and save plots.
table: A logical value indicating whether to generate and save tables
timeseries_analysis: A logical value indicating whether to analysis timeseries.
line_width: A numeric value specifying the line width. Default is 1.5.
point_size: A numeric value specifying the point size. Default is 1.8.
point_alpha: A numeric value specifying the point alpha. Default is 0.7.
point_shape: A numeric or character value specifying the shape of the points. Default is 1.
line_alpha: A numeric value specifying the line alpha. Default is 0.7.
axis_text_size: A numeric value specifying the size of the axis text. Default is 10.
axis_title_size: A numeric value specifying the size of the axis title. Default is 10.
strip_text_size: A numeric value specifying the size of the strip text. Default is 10.
axis_text_face: The font face of the axis text. Default is "plain".
axis_title_face: The font face of the axis title. Default is "bold".
strip_text_face: The font face of the strip text. Default is "bold".
smooth_method: A character string specifying the smoothing method to be used. Default is "loess".
smooth_linetype: A character string specifying the line type for the smoothing curve. Default is "dashed".
line_linewidth: A numeric value specifying the line width for the line geom. Default is 1.5.
text_hjust: A numeric value specifying the horizontal justification of the text geom. Default is 0.9.
text_vjust: A numeric value specifying the vertical justification of the text geom. Default is -4.
text_size: A numeric value specifying the size of the text geom. Default is 4.5.
text_color: A character string specifying the color of the text geom. Default is "black".
facet_ncol: A numeric value specifying the number of columns to be used in facet_wrap. Default is 2.
h_value: The minimum segment size passed to strucchange::breakpoints(): a fraction of the series length (default 0.15) or a number of years.
ZH: A logical value. If TRUE, chart text and names are in Chinese. Default is FALSE. ZH = TRUE is the same as lang = "zh".
lang: The language of the chart text and names: "en" (English), "zh" (Chinese) or "both" (Chinese and English). Default is NULL, which uses "zh" if ZH = TRUE, and otherwise the language set with fao_settings() ("en" unless changed).
pptx: A logical value. Charts are always saved as PNG in figures/png/; if TRUE they are also saved as editable PowerPoint files in figures/pptx/. Default is FALSE, which can be changed for all functions with fao_settings(pptx = TRUE).
plot_show: A logical value. If TRUE, each chart is also drawn in the plot window (e.g. the Plots pane of RStudio) as it is saved, to look at it at once. Default is FALSE, which can be changed for all functions with fao_settings(plot_show = TRUE). The charts are saved as files (plot = TRUE) either way.

Value

A list with area_country (yearly catch of every country in the area), area_country_ranked (yearly catch of the ranked countries, with the others grouped), area_country_ranked_total (total catch and rank of the selected countries) and coefs_data (start year, end year and mean catch of each period between breakpoints). Charts and tables are saved if plot and table are TRUE.

Examples

if (FALSE) { # \dontrun{
FAO27 <- fishing_area_data("Atlantic, Northeast")
fishing_area_country(FAO27$area_data, rank_range = 1:10)    # the ten main countries
fishing_area_country(FAO27$area_data, rank_range = c(5, 6)) # the fifth and sixth
} # }
