geodimension (version 1.0.0)

add_geometry: Add geometry to a level

Description

A level can have several geometries (point, polygon or line). This function adds the geometry of the layer to the level.

Usage

add_geometry(gl, layer = NULL, layer_key = NULL, level_key = NULL)
# S3 method for geolevel
add_geometry(gl, layer = NULL, layer_key = NULL, level_key = NULL)

Value

A geolevel.

Arguments

gl

A geolevel object.

layer

A sf object.

layer_key

A vector of string.

level_key

A vector of string.

Details

The association of the geometry to the existing instances is done through join using the level key and the layer key.

If none is indicated, by default the key defined in the level is considered.

Examples

us_state_point <-
  coordinates_to_geometry(layer_us_state,
                          lon_lat = c("intptlon", "intptlat"))

state <-
  geolevel(name = "state",
           layer = layer_us_state,
           key = c("geoid")) %>%
  add_geometry(layer = us_state_point)
