title: how to stop getting exponents on barchart graph and extending number on y axis
body: <p>I keep getting exponents on the y axis and on top of the bar. How do I change it so it stops showing up as exponents. I am also trying to get the y axis to go up to 8 million.</p>
  <pre><code>obama &lt;- data.frame(date=c(&quot;March 27&quot;, &quot;March 31&quot;),
                      enrollment=c(6000000, 7066000))
  
  
  ggplot(data = obama, aes(x= date, y=enrollment))+
    geom_bar(stat = &quot;identity&quot;)+
    ggtitle(&quot;Obamacare Enrollment&quot;)+
    theme_classic()+
    geom_text(aes(label=enrollment), vjust=-0.3, size=3.5
  </code></pre>
