Build a feature layer from a data frame

Wraps a data frame as a self-contained client side feature collection. This is the iLayer a chart reads and the layer a map draws. No live feature service is involved.

Usage

as_feature_layer(
  .data,
  name = "layer_data",
  title = name,
  id = "arcgisviz-layer",
  drawing_info = NULL,
  opacity = NULL,
  visibility = NULL,
  popup_info = NULL
)

Arguments

.data

Defines which data frame or sf object to convert.

name

default "layer_data". Defines what the layer is named.

title

default name. Defines the human readable layer title.

id

default "arcgisviz-layer". Defines the unique layer id.

drawing_info

default NULL. Defines how features are symbolized, as a list holding a renderer.

opacity

default NULL. Defines the layer opacity, from 0 to 1.

visibility

default NULL. Defines whether the layer starts visible.

popup_info

default NULL. Defines which fields are shown when a feature is hovered or clicked, as a list holding title and fieldInfos.

Value

An IFeatureLayer.

df <- data.frame(species = c("a", "b", "c"), mass = c(1, 5, 3))
