28.1 Equations

Here is an equation.

$$\begin{array}{}f\left(k\right)=(\frac{n}{k})p^k{(1-p)}^{n-k}& \text{(28.1)}\end{array}$$

You may refer to using \@ref(eq:binom), like see Equation (28.1).

28.2 Theorems and proofs

Labeled theorems can be referenced in text using \@ref(thm:tri), for example, check out this smart theorem 28.1.

Theorem 28.1 For a right triangle, if $c$ denotes the length of the hypotenuse and $a$ and $b$ denote the lengths of the other two sides, we have $$a^2+b^2=c^2$$

28.3 Callout blocks

The bs4_book theme also includes special callout blocks, like this .rmdnote.

You can use markdown inside a block.

head(beaver1, n = 5)
  day time  temp activ
1 346  840 36.33     0
2 346  850 36.34     0
3 346  900 36.35     0
4 346  910 36.42     0
5 346  920 36.55     0

It is up to the user to define the appearance of these blocks for LaTeX output.

You may also use: .rmdcaution, .rmdimportant, .rmdtip, or .rmdwarning as the block name.

The R Markdown Cookbook provides more help on how to use custom blocks to design your own callouts: https://bookdown.org/yihui/rmarkdown-cookbook/custom-blocks.html
