title: Getting OVER QUERY LIMIT after one request with geocode
body: <p>I'm using the ggmap's geocode to find the latitude and longitude of different cities. It worked completely fine yesterday but I get an OVER QUERY LIMIT after only one request today.</p>
  
  <p>In fact if I just load the library and run geocode it throws the OVER QUERY LIMIT error:</p>
  
  <pre><code>&gt; library(ggmap)
  &gt; geocode("Paris")
  Information from URL : http://maps.googleapis.com/maps/api/geocode/json?address=Paris&amp;sensor=false
    lon lat
  1  NA  NA
  Warning message:
  geocode failed with status OVER_QUERY_LIMIT, location = "Paris" 
  </code></pre>
  
  <p>I checked different topics on stackoverflow but nobody seems to have the same problem.
  I tried to see if I was over the 2500 limit (very unlikely but I'm new to coding so maybe I did something wrong...) and geocodeQueryCheck() reads 2498 but then again it resets every time I run library(ggmap).</p>
  
  <p>It worked once fifteen minutes ago when I rebooted Rstudio but now it doesn't work anymore, I'm completely lost!</p>
  
  <p>Does anyone have any idea what might be the problem?</p>
  
  <p>PS: I'm new to stackoverflow so if you have any remark on anything please tell me!</p>
