ggmap is using Google Maps as its standard map source.

At the moment, the Google Maps API that ggmap is connecting to needs lon/lat coordinates (e.g., location = c(16.3738,48.2082) - not a location name) and a functioning and registered Google Maps API key (that you register via register_google(key = "...") in every new session) to get a map.

So, the full code for you would be

library(ggmap)
register_google(key = "...") # with your billing-enabled API key entered here
map <- get_map(location = c(31.2357,30.0444), zoom = 5)
ggmap(map)
