Arguments

rdeck	<rdeck | rdeck_proxy> An rdeck map instance.
...	Additional parameters that will be forwarded to deck.gl javascript without validation nor processing. All dots must be named and will be camelCased when serialised. A warning is raised when dots are used, warning class rdeck_dots_nonempty.
id	<string> The layer's identifier must be unique for among all layers of the same type for a map. Defaults to uuid::UUIDgenerate(), but should be explicitly defined for updatable layers in a shiny application.
name	<string> Identifies the layer on tooltips and legends. It does not need to be unique, but should be brief. Defaults to the deck.gl class name for the layer.
group_name	<string> Defines the group that this layer belongs to. Currently only effective on the layer selector, if visibility_toggle = TRUE.
data	<data.frame | sf | string> The layer's data. Data frames and sf objects will contain all columns that are referenced by the layer's accessors. Strings will be interpreted as a URL and data will be retrieved dynamically in the browser.
visible	<boolean> Determines whether the layer is visible or not; also determines whether any legend elements for the layer will be displayed.
pickable	<boolean> Determines if the layer responds to pointer / touch events.
opacity	<number> Determines the layer's opacity.
wrap_longitude	<boolean> Normalises geometry longitudes.
position_format	<"XY" | "XYZ"> Determines whether each coordinate has two (XY) or three (XYZ) elements.
color_format	<"RGB" | "RGBA"> Determines whether the alpha channel of the colours will be ignored by accessors, making all colours opaque.
auto_highlight	<boolean> When TRUE, the current object hovered by the cursor is highlighted by highlight_color.
highlight_color	<accessor | scale | color> When auto_highlight and pickable are enabled, highlight_color determines the colour of the currently highlighted object. If a single colour value is supplied, that colour will be used to highlight all objects in the layer. Per-object highlighting is achieved with a colour scale, or a tidy-eval column of colours.
stroked	<boolean> If TRUE, draw an outline around each object.
filled	<boolean> If TRUE, draw the filled area of each point.
extruded	<boolean> If TRUE, extrude objects along the z-axis; if FALSE, all objects will be flat.
elevation_scale	<number> The elevation multiplier.
wireframe	<boolean> If TRUE and extruded == TRUE, draw a line wireframe of the object. The outline will have horizontal lines closing the top and bottom polygons and vertical lines for each vertex of the polygon.
line_width_units	<"pixels" | "common" | "meters"> The units of line width.
line_width_scale	<number> The line width multiplier.
line_width_min_pixels	<number> The minimum line width in pixels.
line_width_max_pixels	<number> The maximum line width in pixels.
line_joint_rounded	<boolean>
line_miter_limit	number
get_fill_color	<accessor | scale | color> The fill colour of each object. Accepts a single colour value, a colour scale, or a tidy-eval column of colours.
get_line_color	<accessor | scale | color> The line colour of each object. Accepts a single colour value, a colour scale, or a tidy-eval column of colours.
get_line_width	<accessor | scale | number> The outline of the object in units specified by line_width_units. Accepts a single numeric value, a numeric scale, or a tidy-eval column of numbers.
get_elevation	<accessor | scale | number> The elevation to extrude each object in the z-axis. Height units are in metres. Accepts a single numeric value, a numeric scale, or a tidy-eval column of numbers.
material	<boolean>
high_precision	<boolean> If TRUE, draw each hexagon as a polygon using each hexagon's true geometry. If FALSE, draw each hexagon with the same shape as center_hexagon. High precision trades rendering performance for geometry precision. High precision is required (forcibly enabled) when: Rendering hex resolutions in range c(0, 5) Pentagons are present in the data Multiple resolution hexes are present in the data
coverage	<number> Radius multiplier, between 0 - 1. The radius of each disk is calculated by coverage * radius.
center_hexagon	<string> If high_precision == FALSE, defines the H3 hexagon that will be used as the shape of all hexagons in the layer. Defaults to the hexagon in the centre of the viewport.
get_hexagon	<accessor> The H3 hex token for each H3 hexagon. Accepts a tidy-eval character column.
blending_mode	<"normal" | "additive" | "subtractive"> Sets the blending mode. Blending modes: normal: Normal blending doesn't alter colours of overlapping objects. additive: Additive blending adds colours of overlapping objects. Useful for highlighting dot density on dark maps. subtractive: Subtractive blending darkens overlapping objects. Useful for highlighting dot density on light maps.
visibility_toggle	<boolean> Whether this layer will appear in the layer selector.
tooltip	<tooltip> Defines the columns (and their order) that will be displayed in the layer tooltip, if pickable == TRUE. Supports tidy-select if a data is a data.frame. Geometry columns are always removed.
