The maps

One verb per question a map answers. Each resolves land, projection and a colour scale chosen for the quantity, and says so in the figure when it had to decide something.

map_surface()
Map a predicted surface
map_probability()
Map a probability
map_diverging()
Map a quantity with a meaningful centre
map_pair()
A surface and its uncertainty, as one figure
map_panels()
The same geography over several periods, on one scale
map_effort()
Map survey effort and detections
hex_surface()
Bin point values into a hexagonal surface

Interactive

The same maps as leaflet widgets, built from the same scale objects so a cell is the same colour in both renderers. A pair and a series become a layer switch on one map rather than two maps.

leaflet_surface() leaflet_probability() leaflet_diverging()
Interactive versions of the maps
leaflet_pair()
A surface and its uncertainty, interactively
leaflet_panels()
A series over several periods, interactively

What the maps are built from

The data contract, the coastline, and the two coordinate-system questions – what a map is drawn in and what areas are measured in – answered separately on purpose.

as_map_data()
Put spatial model output into the form the maps draw from
coastline() coastline_fixture()
A coastline for a map
display_crs()
The coordinate system a map is drawn in
equal_area_crs()
The coordinate system areas and distances are computed in
area_km2()
Areas in square kilometres, computed honestly

Scales

How a surface should be coloured, decided by stated rules and reported when a rule fires. See vignette(“scales”) for the argument.

surface_scale()
How a surface should be coloured
diverging_scale()
How a diverging surface should be coloured
fancymap_palette()
The colour ramps these maps use

Furniture and style

Scale bar, north arrow, locator inset, and the theme shared with fancyfx.

scale_bar()
A scale bar, sized for the panel it is drawn in
north_arrow()
A north arrow
locator_inset()
A locator inset
theme_fancymap()
A theme for maps
theme_fancymap_panel()
The map theme as used inside a multi-panel figure

Example data

example_grid()
A small example grid
