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 classrdeck_dots_nonempty
.- id
<
string
> The layer's identifier must be unique for among all layers of the same type for a map. Defaults touuid::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, ifvisibility_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
> WhenTRUE
, the current object hovered by the cursor is highlighted byhighlight_color
.- highlight_color
<
accessor
|scale
|color
> Whenauto_highlight
andpickable
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.- size_units
<
"pixels"
|"common"
|"meters"
> The units of the size specified byget_size
.- point_size
<
number
> The radius of all points in units specified bysize_units
.- get_position
<
accessor
> The feature positions. A<point/multipoint>
wk-geometry column with CRS EPSG:4326. Supports tidy-eval.- get_normal
<
accessor
|numeric
> The normal of each object, inc(nx, ny, nz)
. Accepts a length-3 numeric vector, or a tidy-eval 3-column matrix column.- get_color
<
accessor
|scale
|color
> The colour of each object. Accepts a single colour value, a colour scale, or a tidy-eval column of colours.- 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, ifpickable == TRUE
. Supports tidy-select if adata
is adata.frame
. Geometry columns are always removed.
