)Arguments
- x
An 'indicator_map' object containing indicator values associated with map grid cells.
- title
Plot title. Replace "auto" with your own title if you want a custom title or if calling the function manually.
- auto_title
Text for automatic title generation, provided by an appropriate S3 method (if calling the function manually, leave as NULL).
- leg_label_default
Default label for the legend, provided by an appropriate S3 method (if calling the function manually, leave as NULL).
- xlims
(Optional) Custom x-axis limits.
- ylims
(Optional) Custom y-axis limits.
- trans
(Optional) Scale transformation for the fill gradient (e.g., 'log').
- bcpower
(Optional) Power parameter for the Box-Cox, modulus, or Yeo-Johnson transformations.
- breaks
(Optional) Break points for the legend scale.
- labels
(Optional) Labels for legend scale break points.
- crop_to_grid
If TRUE, the grid will determine the edges of the map.Overrides Europe_crop_EEA. Default is FALSE.
- panel_bg
(Optional) Background colour for the map panel.
- land_fill_colour
(Optional) Colour for the land area outside of the grid (if surround = TRUE). Default is "grey85".
- legend_title
(Optional) Title for the plot legend.
- legend_limits
(Optional) Limits for the legend scale.
- legend_title_wrap_length
Maximum legend title length before wrapping to a new line.
- title_wrap_length
Maximum title length before wrapping to a new line.
- visible_gridlines
Show gridlines between cells. Default is TRUE.
- layers
Additional rnaturalearth layers to plot, e.g. c("reefs", "playas").
- scale
Scale of Natural Earth data ("small", "medium", or "large"). Default is 'medium'.
Value
A ggplot object representing the biodiversity indicator map. Can be customized using ggplot2 functions.
