title: Registering API key in R for ggmap
body: <p>I'm trying to retrieve a map of the UK with the package <code>ggmap</code> in R and believe I'm having trouble due to Google's relatively new API terms and conditions from this year. </p>
  
  <pre><code>install.packages("ggplot2")
  library("ggplot2")
  install.packages("devtools")
  library("devtools")
  devtools::install_github("dkahle/ggmap")
  library(ggmap)
  </code></pre>
  
  <p>I'm attempting to register my key below for my R session, but when I use my API key I receive the error code in R <code>object not found</code>. I have not included my key below.</p>
  
  <pre><code>register_google(key)
  </code></pre>
  
  <p>I'm getting this error for the map:</p>
  
  <blockquote>
    <p>Forbidden (HTTP 403)</p>
  </blockquote>
  
  <p>for the code directly below:</p>
  
  <pre><code>map_UK &lt;- get_map(location = "United Kingdom", zoom = 4)
  </code></pre>
  
  <p>I've given billing credentials to Google API and enabled all of the Google Maps features. I would appreciate any help with this. </p>
