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.
When a ≠ 0, there are two solutions to ax2 + bx + c = 0 and they are
BAD IDEA!!
Info
Figures and tables with captions will be placed in figure
and table
environments, respectively.
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.

You can write citations, too. For example, we are using the bookdown package (Xie 2020) in this sample book, which was built on top of R Markdown and knitr (Xie 2015).
