Other types of formatting include:

*italics*

**bold**

`code box`

looks like a div container

superscript^2^/subscript~2~

superscript²/subscript₂

~~strikethrough~~

Use <br> to force a line break (in html)
Or use double spaces at the end of the line to force one in word

Lists and Dividers

- unordered list
- item 2
  - item 2a (indent 1 tab)
  - item 2b
ordered list

• unordered list
• item 2
  • item 2a (indent 1 tab)
  • item 2b

1. ordered list
2. item 2
 - item 2a (indent 2 tabs)
 - item 2b
ordered list

1. ordered list
2. item 2
   • item 2a (indent 2 tabs)
   • item 2b

Three dashes in a row (---) create a line break like the one after this chunk.

Font Colors

Font colors can be changed in HTML, but word will ignore this formatting.

<span style="color: red;">This text will be red</span>

This text will be red

Basic Plots and Formatting

basic r plots are made with the formula plot()

car <- mtcars
plot(mpg ~ disp,
     data = mtcars,
     xlab = "Displacement (cu. in)",
     ylab = "Miles per Gallon",
     col = "hotpink")

By default plots will execute separately.

plot(mpg ~ disp,
     data = mtcars,
     xlab = "Displacement (cu. in)",
     ylab = "Miles per Gallon",
     col = "hotpink")

hist(mtcars$cyl,
     col = "green4",
     main = "Cylinder Count")

You can change this with par(mfrow)

The format of par(mfrow) is row, column, so this will print one on top of the other:

par(mfrow = c(2, 1))

plot(mpg ~ disp,
     data = mtcars,
     xlab = "Displacement (cu. in)",
     ylab = "Miles per Gallon",
     col = "hotpink")

hist(mtcars$cyl,
     col = "green4",
     main = "Cylinder Count")

And this will print side by side, but notice how it is left-aligned.

par(mfrow = c(1, 2))

plot(mpg ~ disp,
     data = mtcars,
     main = "MPG vs Displacement",
     xlab = "Displacement (cu. in)",
     ylab = "Miles per Gallon",
     col = "hotpink")

hist(mtcars$cyl,
     col = "green4",
     main = "Cylinder Count")

Alignment is changed in the chunk.

{r, fig.align = ‘center’}

par(mfrow = c(1, 2))

plot(mpg ~ disp,
     data = mtcars,
     main = "MPG vs Displacement",
     xlab = "Displacement (cu. in)",
     ylab = "Miles per Gallon",
     col = "hotpink")

hist(mtcars$cyl,
     col = "green4",
     main = "Cylinder Count")
