Usage

get_navermap(
  center = c(lon = 126.9849208, lat = 37.5664519),
  zoom = 4,
  size = c(640, 640),
  format = c("png", "jpeg", "jpg"),
  crs = c("EPSG:4326", "NHN:2048", "NHN:128", "EPSG:4258", "EPSG:4162", "EPSG:2096",
    "EPSG:2097", "EPSG:2098", "EPSG:900913"),
  baselayer = c("default", "satellite"),
  color = c("color", "bw"),
  overlayers = c("anno_satellite", "bicycle", "roadview", "traffic"),
  markers,
  key,
  uri,
  filename = NULL,
  messaging = FALSE,
  urlonly = FALSE,
  force = FALSE,
  where = tempdir(),
  archiving = TRUE,
  ...
)

Arguments

center	the center of the map. this can be longitude/latitude numeric vector.
zoom	map zoom, an integer from 1 to 14 (building), default value 10
size	rectangular dimensions of map in pixels - horizontal x vertical - with a max of c(640, 640).
format	character string providing image format - png, jpeg(jpg) formats available in various flavors
crs	Coordinate system, this currently supports EPSG:4326
baselayer	base layer, this can be either "default", "satellite".
color	color or black-and-white
overlayers	overlay layers, this can be "anno_satellite","bicycle", "roadview", "traffic".
markers	data.frame with first column longitude, second column latitude, for which naver markers should be embedded in the map image, or character string to be passed directly to api
key	key code from naver api center
uri	registered host url
filename	destination file for download (file extension added according to format). Default NULL means a random tempfile().
messaging	turn messaging on/off
urlonly	return url only
force	if the map is on file, should a new map be looked up?
where	where should the file drawer be located (without terminating "/")
archiving	use archived maps. note: by changing to TRUE you agree to abide by any of the rules governing caching naver maps
