title: Adjust the number of ticks on y axis, barplot() in R
body: <p>I need make few things to get more ticks on y axis, as shown in the image below, but I am not managing to do that. Any help will be appreciated a lot!
  This far I have typed:</p>
  
  <pre><code>Temp&lt;-table(airquality$Temp)
  barplot(Temp, col = "red", border = "blue",xpd = FALSE)
  </code></pre>
