我正在尝试使用 ggmap 库和 osm 背景在 R 上构建地图,但是出现以下错误。
library(ggmap) library(osmdata) library(devtools)
mad_map <- get_map(getbb("Limete, Kinshasa"), maptype = "terrain", source = "osm")
Erreur : 'get_openstreetmap' is defunct.Use 'OSM is at least temporarily not supported, see https://github.com/dkahle/ggmap/issues/117.' instead.
