title: Scatter plot of two different data frames r
body: <p>I'm very new to R and searched quite a bit but couldn't find an answer to this question. </p>
  
  <p>I have two data frames that are formatted exactly the same way, where rows equal countries and columns equal years. I want to create a scatter plot where data frame 1 is X and data frame 2 is Y.</p>
  
  <p>For example:</p>
  
  <pre><code> Data frame 1:
  
          1991  1992
   USA       1     3
   Canada    4     5
  
  
   Data frame 2:
  
          1991  1992
   USA     200   129
   Canada  245   342
  </code></pre>
  
  <p>Any suggestion for how I should being?</p>
