Markdown Syntax

If you type…	Output
`italics`	italics
`bold`	bold
`*bold italics*`	*bold italics*
`- chai tea - green tea - earl grey tea`	chai tea green tea earl grey tea
`[this is the text that will display](www.google.com)`	this is the text that will display
`![a caption here](jellyfish.jpg)`

R chunks

Tip

To create a R chunk:

use the +C green buttom in the top menu
Mac Shortcut: CMD + OPTION + I
PC shortcut: Ctrl + ALT + I
manually type out ```{r}… etc.

Calculations and R code goes inside chunks.

2+2

[1] 4

Operator	Description
`+`	Addition
`-`	Subtraction
`*`	Multiplication
`/`	Division
`^` or `**`	Exponentiation
`x %% y`	Modulus (x mod y) → `5 %% 2 = 1`
`x %/% y`	Integer division → `5 %/% 2 = 2`

Commenting inside an R chunk:

# anything behind a "#" in an R chunk is a comment

Assigning a value to an object:

# this takes the value of 20 and assigns it to the object x
x <-11

Operations with objects:

# take the object x, multiply by 2, and spit out the answer
y <- x*2
y

[1] 22

Creating a vector:

z <- c(1.778, 1.53, 1.58, 1.56)
# c stands for concatenate -- a fancy computer science word for "put together"

z_inches <- z*39.701

# This calculates the mean of z
mean(z, na.rm=TRUE)

[1] 1.612

# This calculates the standard deviation of z
sd(z)

[1] 0.1125581

Equations

Centered and large equations

Type in the plain text section:

$$y=\frac{x^2}{SE(x^2)} $$

Displays as:

\[y=\frac{x^2}{SE(x^2)} \]

Hint: Some people like to use the visual editor to insert equations

Inline equations

Type in the plain text section:

We take and calculate the standard error $SE(x_1)$.

Displays as:

We take and calculate the standard error $SE(x_1)$.

Inline code

Type in the plain text section:

This is a sentence. The value of x is `r x`

Displays as:

This is a sentence. The value of x is 11.
