I have been facing this issue in the get_map() function (ggmap library) in R.

My code was running without the need to specify an API key

    I don't know the direct resolution to the ggmap issue, but if you're happy to work with an interactive map rather than a static one you can use my googelway library

    library(googleway)
    
    set_key("GOOGLE_MAP_KEY")
    
    lat <- c(4,41) #India lat boundaries
    lon <- c(68,99) #India long boundaries
    center = c(mean(lat), mean(lon))
    
    google_map(location = center, zoom = 6)

    Just adding to @Roman's response, here's the code that worked for me:

    if(!requireNamespace("devtools")) install.packages("devtools")
    devtools::install_github("dkahle/ggmap", ref = "tidyup")
    library(ggmap)
    register_google(key = "your_API_key") 
    usa<- get_googlemap(location='united states', zoom=4,maptype = "hybrid")
    

    For more information you could refer to the library page on github: here
    Hopefully it helps!

    You need to use register_google(key = "...") in every new session of R. Using api_key = inside the get_map() call does not work.


    updated: 2018-12-24 for ggmap 2.7.904 and current Google Cloud API

    Step-by-Step Tutorial

    1. Update to newest version of ggmap

    require(devtools)
    devtools::install_github("dkahle/ggmap", ref = "tidyup")
    

    2. Activate your Google API key for all APIs in the Google Cloud Console

    • Link for more info on how to get an API key

    • Direct Link to Google Cloud Platform Console

    • Direct Link to Google Maps API Pricing Information

    • APIs you need: Maps Static and Geocoding

    • Enable billing in the general settings.

    3. Load ggmap and register key

    library(ggmap)
    register_google(key = "...")     # copied directly from Google Console via 'copy' button
    

    4. Plot default map

    ggmap(get_googlemap())          
    

    5. Plot with location name (Geocoding)

    ggmap(get_map("Hannover, Germany"))
    

    If you get an error here (e.g., Forbidden 403) you most probably have not activated your key for the right APIs. Tutorial to troubleshoot geocoding

    6. Plot with longitude and latitude

    ggmap(get_map(location=c(16.3738,48.2082), zoom=13, scale=2))

    Just to add to Roman Abashin's answer (I can't comment, unfortunately): As per '?get_map()', the 'api_key =' argument doesn't work for Google maps. You'll need to use the 'register_google()' function, but as of 03/10/18, it's only in the development version of ggmap, which you can get like so:

    devtools::install_github("dkahle/ggmap", ref = "tidyup")
    

    Then you'll also need to enable billing on your Google account, though the first 100,000 maps you use each month should be free, see here: https://cloud.google.com/maps-platform/pricing/sheet/ for details.
