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.
get_tile_data	<JS> retrieves the data of each tile. See deck.gl getTileData.
extent	<c(min_x, min_y, max_x, max_y)> Tiles in this bounding box will be rendered at min_zoom, when zoomed out below min_zoom.
tile_size	<number> A power of 2 that is the pixel dimensions of the tile.
max_zoom	<number> Tiles above this zoom level are not shown. Defaults to NULL.
min_zoom	<number> Tiles below this zoom level are not shown. Defaults to 0.
max_cache_size	<number> Maximum number of tiles that can be cached. Defaults to 5x the number of tiles in current viewport.
max_cache_byte_size	<number> Maximum memory used for caching tiles.
refinement_strategy	<"best-available" | "no-overlap" | "never"> How the tile layer refines visibility of tiles. Defaults to "best-available".
z_range	<c(min, max)> Array representing the range of heights in the tile.
max_requests	<number> Maximum number of concurrent HTTP requests across all specified tile provider domains. If a negative number is supplied no throttling occurs (HTTP/2 only).
zoom_offset	<int> The offset changes the zoom level at which the tiles are fetched.
elevation_data	url
texture	not yet supported.
mesh_max_error	number
bounds	<rct/st_bbox/wk-geometry> The bounds of the image to fit x,y coordinates into. Requires CRS EPSG:4326. Must be supplied when using non-tiled elevation data.
color	color
elevation_decoder	object
worker_url	string
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.
material	<boolean>
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.
