title: How to select from multiple table within a dataset in Big Query using dplyr and bigrquery?
body: <p>I'm trying to query multiple tables from a dataset in Big Query using dplyr and bigrquery. The dataset holds multiple tables, one for each day of data in a year. 
  I can query from a single table (e.g., 1 day of data) with the following code but cant seem to make it work across multiple tables at once (e.g., for a month or year of data) . Any help would be greatly appreciated.</p>
  
  <pre><code>connection &lt;- src_bigquery("my_project", "dataset1")
  first_day &lt;- connection %&gt;%
      tbl("20150101") %&gt;% 
      select(field1) %&gt;%
      group_by(field1) %&gt;%
      summarise(number = n()) %&gt;%
      arrange(desc(number))
  </code></pre>
  
  <p>Thank you, </p>
