osm_structures

Description

For the given vector of structure types returns a data.frame containing two columns of corresponding OpenStreetMap key-value pairs, one column of unambiguous suffixes to be appended to the objects returned by extract_osm_objects, and one column specifying colours. This data.frame may be subsequently modified as desired, and ultimately passed to make_osm_map to automate map production.

Usage

osm_structures(
  structures = c("building", "amenity", "waterway", "grass", "natural", "park",
    "highway", "boundary", "tree"),
  col_scheme = "dark"
)

Arguments

structures	The vector of types of structures (defaults listed in extract_osm_objects).
col_scheme	Colour scheme for the plot (current options include dark and light).

Value

data.frame of structures, key-value pairs, corresponding prefixes, and colours.

See Also

make_osm_map.

Other construction: add_osm_objects(), make_osm_map(), osm_basemap(), print_osm_map()

Examples

# Default structures:
osm_structures ()
# user-defined structures:
structures <- c ("highway", "park", "ameniiy", "tree")
structs <- osm_structures (structures = structures, col_scheme = "light")
# make_osm_map returns potentially modified list of data
## Not run: 
dat <- make_osm_map (osm_data = london, structures = structs)
# map contains updated $osm_data and actual map in $map
print_osm_map (dat$map)

## End(Not run)
