title: plotting 2 datasets with unequal lengths using ggplot2
body: <p>I have 2 datasets with unequal lengths for plotting using ggplots2:</p>
  
  <pre><code>Data A;
  
  column x column y
  0.23     1.54    
  0.44     1.46
  0.69     1.37
  0.70     1.21
  0.75     1.01
  0.88     0.91 
  
  Data B:
  
  column x column y
  0.13     1.24    
  0.34     1.16
  0.49     1.07
  0.54     0.99
  0.69     1.01
  </code></pre>
  
  <p>I'm sure of how to write a code in ggplot2 for plotting these two data sets together. In both cases, plots shown as x axis = column x and y axis= column y. Can someone help me please?</p>
