geodimension (version 1.0.0)

get_level_layer: Get level layer

Description

Get a geographic layer associated with a level. We can select the geometry and, using boolean parameters, which attributes are included in the layer's table: only the attributes that make up the key, the subrogate key, inherited attributes.

Usage

get_level_layer(
  gd,
  level_name = NULL,
  geometry = NULL,
  only_key = FALSE,
  surrogate_key = FALSE,
  inherited = FALSE,
  add_prefix = TRUE
)
# S3 method for geodimension
get_level_layer(
  gd,
  level_name = NULL,
  geometry = NULL,
  only_key = FALSE,
  surrogate_key = FALSE,
  inherited = FALSE,
  add_prefix = TRUE
)

Value

A sf object.

Arguments

gd

A geodimension object.

level_name

A string.

geometry

A string.

only_key

A boolean.

surrogate_key

A boolean.

inherited

A boolean.

add_prefix

A boolean.

Details

In case of inheriting attributes from other levels, in the table, these can have as a prefix the name of the level in uppercase.
