title: Import schema into BigQuery via R
body: <p>I have a folder containing:</p>
  <pre><code>-- schema.yml
  -- table1.csv
  -- table2.csv
  -- table4.csv
  </code></pre>
  <p>This folder is stored locally.</p>
  <p>I looked around for a while and I want to ask:</p>
  <p>Is there a way to batch upload this schema into BigQuery directly from R?</p>
