title: "API rate limit exceeded" when trying to install local R package using devtools::install()
body: <p>Package development beginner here! </p>
  
  <p>I'm trying to turn some code into a local R package for the very first time. I made a package using <code>usethis::create_package()</code>, added documentation using <code>devtools::document()</code>. </p>
  
  <p>Now, after playing around with it for a while, I ran into the following error when trying to install the newest version using <code>devtools::install()</code>: </p>
  
  <pre><code>Error: HTTP error 403.
    API rate limit exceeded for [my IP]. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)
  
    Rate limit remaining: 0/60
    Rate limit reset at: 2019-03-18 16:32:05 UTC
  
    To increase your GitHub API rate limit
    - Use `usethis::browse_github_pat()` to create a Personal Access Token.
    - Use `usethis::edit_r_environ()` and add the token as `GITHUB_PAT`.
  </code></pre>
  
  <p>The problem <em>still</em> exists if I use <code>devtools:install_local("my_folder_name")</code>. What genuinely confuses me here is that I am hitting a GitHub rate limit by trying to install a package sitting in a local folder. </p>
  
  <p>Did I make a mistake in the package setup, or does using <code>devtools::install()</code> always involve the GitHub API? 
  Is there anything I can change to keep the installation process of my package local and thus avoid the rate limit issue?</p>
