Get a geolayer object

Source: R/geolayer.R
as_geolayer.Rd

From a star_database with at least one geoattribute, we obtain a geolayer object that allows us to select the data to obtain a vector layer with geographic information.

Usage

as_geolayer(db, dimension, attribute, geometry, include_nrow_agg)

# S3 method for class 'star_database'
as_geolayer(
  db,
  dimension = NULL,
  attribute = NULL,
  geometry = NULL,
  include_nrow_agg = FALSE
)

Arguments

db

An star_database object.

dimension

A string, dimension name.

attribute

A vector, attribute names.

geometry

A string, geometry name.

include_nrow_agg

A boolean, include default measure.

Value

A geolayer object.

Details

If only one geographic attribute is defined, it is not necessary to indicate the dimension or the attribute. By default, polygon geometry is considered.
