Plot spatial indicators

Plots the output of calc_spatial_indicators() as time-series panels, one panel per indicator variable. When the input contains multiple length groups, all groups are overlaid as coloured lines within each panel.

Usage

plot_spatial_indicators(
  x,
  vars = NULL,
  x_var = NULL,
  col = NULL,
  lwd = 2,
  pch = NULL,
  legend = TRUE,
  legend_pos = "topright",
  layout = TRUE,
  xlim = NULL,
  main = NULL
)

Arguments

x: Data frame returned by calc_spatial_indicators().
vars: Character vector of column names to plot. Defaults to all indicator columns detected in x (cog_lat and cog_lon).
x_var: Name of the x-axis column. Defaults to "Year" if present, otherwise the first non-result column.
col: Character vector of colours, one per unique group. Defaults to the DATRASextra discrete palette.
lwd: Line width. Default 2.
pch: Integer vector of point symbols, one per unique group. If NULL (default), a built-in sequence of distinct symbols is used.
legend: Logical; draw a legend for group colours. Default TRUE; suppressed automatically when there is only one group.
legend_pos: Legend position string passed to graphics::legend(). Default "topright".
layout: Logical; when TRUE (default) and there are multiple indicator panels, the function sets par(mfrow) automatically and restores it on exit. Set to FALSE to draw panels sequentially into the caller's current layout – useful when combining with other plots via par(mfrow = ...).
xlim: Optional x-axis limits.
main: Optional overall title prefix. If multiple panels are drawn, the indicator name is appended.

Value

Invisibly returns x.

Examples

if (FALSE) { # \dontrun{
data(dab)
dab <- add_swept_area(dab)
dab <- add_total_numbers_by_haul(dab)
res <- calc_spatial_indicators(dab, by = "Year")
plot_spatial_indicators(res)
plot_spatial_indicators(res, vars = "cog_lat")
} # }
