as_geolayer: Get a 'geolayer' object

In rolap: Obtaining Star Databases from Flat Tables

Get a geolayer object

Description

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.

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.

Value

A geolayer object.
