Chapter 2 Introduction
You can label chapter and section titles using {#label}
after them, e.g., we can reference Chapter 2. If you do not manually label them, there will be automatic labels anyway, e.g., Chapter 4.
Figures and tables with captions will be placed in figure
and table
environments, respectively.
par(mar = c(4, 4, 0.1, 0.1))
plot(pressure, type = "b", pch = 19)
Reference a figure by its code chunk label with the fig:
prefix, e.g., see Figure 2.1. Similarly, you can reference tables generated from knitr::kable()
, e.g., see Table 2.1.
knitr::kable(
head(iris, 20), caption = 'Here is a nice table!',
booktabs = TRUE
)

You can write citations, too. For example, we are using the bookdown package (Xie 2016) in this sample book, which was built on top of R Markdown and knitr (Xie 2015). ddd aaa
