Get elements from a RoboCupRescue Simulation map

get_elements.Rd

These functions provide methods to extract specific geographical elements from an rrs_map object. You can retrieve all elements of a certain type or filter them by their IDs.

Usage

get_nodes(map, ids = character())

get_edges(map, ids = character())

get_roads(map, ids = character())

get_buildings(map, ids = character())

get_entrances(map, ids = character())

get_passage(map, ids = character())

Arguments

map

An object of class rrs_map.

ids

A character vector of element IDs to filter by. If empty (default), all elements of the specified type are returned.

Value

An sf data frame containing the requested map elements.

Examples

gml <- system.file("extdata", "map-test.gml", package = "rrstools")
map <- read_rrs_map(gml)
