title: Include variable value on data frame name
body: <p>I'm trying to figure out how can I add something to a data frame <code>df</code>, based on a variable (i.e. a date), ending up with a data frame named <code>df_17</code> if variable is equal to 2017 for example.</p>
  
  <p>The reason why I want this is because I'm importing datasets from several years and quarters, and I would like to make sure that they are named according to the year variable they have. Each dataset only has 1 date. I know I can do it manually but it would take me less time to automate it.</p>
  
  <p>I know how to do it with columns and rows, but I can't figure it out for objects.</p>
  
  <p>EDIT:</p>
  
  <p>Example 1:
  Data frame name "df"</p>
  
  <pre><code>A   B   Date
  1   4   2017
  2   3   2017
  </code></pre>
  
  <p>New data frame name "df_2017"</p>
  
  <p>Example 2:
  Data frame name "df"</p>
  
  <pre><code>A   B   Date
  1   4   2016
  2   3   2016
  </code></pre>
  
  <p>New data frame name - "df_2016 "</p>
