ggmap 3.0.1

New features

• geocode_cache() is now exported to the user, and functions write_geocode_cache() and write_geocode_cache() exist to facilitate using the same cache across sessions.

Changes

• ggmap no longer depends on rjson (thanks @MichaelChirico, #317).
• Most functions now use cli-based messaging functions, following ggplot2’s lead.

Minor improvements and fixes

• ggmap functions can now be called even if it has not been attached to the search path (loaded) (reported by @jennybc, @lorenzwalthert, #264, #244).

• Google functions now properly encode #’s (reported by @aaronrudkin, #272).

• get_stamenmap() now only returns URLs if messaging = TRUE (Reported by @ikosmidis, #274). It also includes a more formal attribution to Stamen Design and OpenStreetMap.

• get_stamenmap() now supports a SSL Stamen endpoint via the https argument (#276).

• mapdist() now properly orders results (reported by @BirgerNi, #266).

• mapdist() now properly returns URLs if urlonly = TRUE.

• get_map() now (again) respects the source = "google" specification when given a bounding box (reported by @julovi, #267).

• geocode() now (again) respects the source = "dsk" specification (reported by @alistaire47, #180).

• A bug giving an error message Error in aperm.default(map, c(2, 1, 3)) : invalid first argument, must be an array has now been fixed. (solution by @kent37, #262).

• geocode() now properly caches when geocoding several locations. The caching keys are now the hash values of the scrubbed url.
