title: Labels geom_bar in ggplot R
body: <p>I have this code</p>
  
  <pre><code>ggplot(authors_interest_sex_count, aes(Country, freq, fill=Gender)) + 
  geom_bar(stat="identity", position="dodge") + geom_text(aes(label = freq), vjust=-1)
  </code></pre>
  
  <p>and I got this image:

  <p>as you can see, the labels for each country are completely vertical, and I think the optimal solution would having each label on top of their column. What should I change or add in my code? Thanks in advance!</p>
