osmplotr (version 0.3.2)

osm_structures: 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.

Examples

# NOT RUN {
# 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)
# }
