Chapter 10 tables

10.1 how to make tables

You can label chapter and section titles using {#label} after them, e.g., we can reference Chapter 10. If you do not manually label them, there will be automatic labels anyway, e.g., Chapter ??.

Figures and tables with captions will be placed in figure and table environments, respectively.

par(mar = c(4, 4, .1, .1))
plot(pressure, type = 'b', pch = 19)
Here is a nice figure!

Figure 10.1: Here is a nice figure!

Reference a figure by its code chunk label with the fig: prefix, e.g., see Figure 10.1. Similarly, you can reference tables generated from knitr::kable(), e.g., see Table 10.1.

knitr::kable(
  head(iris, 20), caption = 'Here is a nice table!',
  booktabs = TRUE
)
Table 10.1: Here is a nice table!
Sepal.Length Sepal.Width Petal.Length Petal.Width Species

5.0 3.4 1.5 0.2 setosa
4.4 2.9 1.4 0.2 setosa
4.9 3.1 1.5 0.1 setosa
5.4 3.7 1.5 0.2 setosa
4.8 3.4 1.6 0.2 setosa
4.8 3.0 1.4 0.1 setosa
4.3 3.0 1.1 0.1 setosa
5.8 4.0 1.2 0.2 setosa
5.7 4.4 1.5 0.4 setosa
5.4 3.9 1.3 0.4 setosa
5.1 3.5 1.4 0.3 setosa
5.7 3.8 1.7 0.3 setosa
5.1 3.8 1.5 0.3 setosa

You can write citations, too. For example, we are using the bookdown package (Xie 2021) in this sample book, which was built on top of R Markdown and knitr (Xie 2015).
