title: I want to put 3 boxplots from 3 different datasets into one graph in R
body: <p>I have 3 different datasets od scores, named aerobic1, aerobic2 and aerobic3. There is only one column of scores in each dataset but I have them in different datasets because aerobic1 has 42 measurements, aerobic2 has 20 and aerobic3 has 19. </p>
  
  <p>I would like to show these 3 datasets as boxplots on the one graph with titles for each boxplot. Can anyone help?? Sorry, I'm just a beginner with R</p>
  
  <p>I tried this code below from a previous post but the problem is, the 3rd boxplot is half off the screen and the scale on Y is -2 to +2 whereas my data ranges from scores of 45 to 180. any help much appreciated</p>
  
  <pre><code>set.seed(1)
  aerobic1 &lt;- rnorm(100)
  aerobic2 &lt;- rnorm(100)
  aerobic3 &lt;- rnorm(100)
  
  boxplot(aerobic1, at=1, xlim=c(0, 3))
  boxplot(aerobic2, at=2, add=TRUE)
  boxplot(aerobic3, at=3, add=TRUE)
  </code></pre>
