I am having difficulty finding out how to include five-number summaries on a graph of side-by-side boxplots. I would like to include a five-number summary for each of 2 boxplots on one graph.

I was wondering if someone could please assist me. Thank you in advance for any help you maybe able to provide.

If it is helpful, the code I have used so far is as follows:

Code:

```
> cheese.matrix <- matrix (
+ c(310,220,420,240,45,180,40,90,270,130,180,260,250,340,290,310),
+ nrow=8,
+ ncol=2)
> boxplot.cheesedata <- boxplot(cheese.matrix, use.cols = TRUE, horizontal = TRUE, xlab = "Sodium Content", main = “Sodium Content of Two Types of Cheese", names=c("Real Cheese", "Cheese Substitute"))
```
