Emphasizing Words

To italisize a word use the asterisk (Shift 8) *italisize*. To bold a word use the double asterisk **bold**. (Notice how the back tic ` can be used to emphasize words as well.)


Bullet Points

Simple Lists

To achieve the result:

  • This is the first item.

  • This is the second.

  • This is the third.

Use the code:

* This is the first item.

* This is the second.

* This is the third.

Numbered Lists

To achieve the result:

  1. This is the first item.

  2. This is the second.

  3. This is the third.

Use the code:

1. This is the first item.

2. This is the second.

3. This is the third.

Lettered Lists

To achieve the result:

  1. This is the first item.

  2. This is the second.

  3. This is the third.

Use the code:

A) This is the first item.

B) This is the second.

C) This is the third.

Nested Lists

  1. What is \(2+2\)?

    1. 4

    2. 8

  2. What is \(3\times5\)?

    1. 14

    2. 15

1. What is $2+2$?

    a. **4**
    
    b. 8
  
2. What is $3\times5$?

    a. 14
    
    b. **15**

Math Equations

Use the dollar signs $x=5$ to write \(x=5\) or $z=\frac{x-\mu}{\sigma}$ to write \(z=\frac{x-\mu}{\sigma}\). For a nicely centered equation use the double dollar signs $$ $$ on separate lines

$$
  z = \frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}
$$

to get \[ z = \frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}} \]

Or

$$
  H_0: \mu_1 = \mu_2
$$
$$ 
  H_a: \mu_1 \neq \mu_2
$$

to get \[ H_0: \mu_1 = \mu_2 \] \[ H_a: \mu_1 \neq \mu_2 \]

Tables

There are many ways to make tables in R Markdown. Here is a simple way to make a “pipe” table.

| Name          | Age           | Gender       | 
|---------------|---------------|--------------|
| Jill          | 8             |  Female      |
| Jack          | 9             |  Male        |
Name Age Gender
Jill 8 Female
Jack 9 Male


Themes

Notice in the YAML (at the top of the RMD file) there is a line that reads:

“theme: cerulean”

Other possible themes are

You can also change the highlighting by adding the line “highlight: tango” to the YAML as follows.

---
title: "Markdown Hints"
output: 
  html_document:
    theme: cerulean
    highlight: tango
---

Other highlighting options are
