R Markdown Introduction

Set up the size of plots in the output

A few additional options: warning=FALSE and message=FALSE suppress any R warnings or messages from being included in the final document; fig.width=5, fig.height=4) set up the size of plots.

I. Headings: There are six levels of headings.

Header 1

Header 2

Header 3

Header 4

Header 5

Header 6

II. Emphasis

Italic Italic Bold Bold

III. Lists

• Mean

• Variance

• SD

• Mean

1. Mean
2. Variance
3. SD
4. s.e.

IV. Links

RStudio R Markdown

V. Images

VI. Code Chunks: Import data and summarize data

tips <- read.csv("http://www.ggobi.org/book/data/tips.csv")
library(knitr)
kable(summary(tips))

	obs	totbill	tip	sex	smoker	day	time	size
	Min. : 1.00	Min. : 3.07	Min. : 1.000	Length:244	Length:244	Length:244	Length:244	Min. :1.00
	1st Qu.: 61.75	1st Qu.:13.35	1st Qu.: 2.000	Class :character	Class :character	Class :character	Class :character	1st Qu.:2.00
	Median :122.50	Median :17.80	Median : 2.900	Mode :character	Mode :character	Mode :character	Mode :character	Median :2.00
	Mean :122.50	Mean :19.79	Mean : 2.998	NA	NA	NA	NA	Mean :2.57
	3rd Qu.:183.25	3rd Qu.:24.13	3rd Qu.: 3.562	NA	NA	NA	NA	3rd Qu.:3.00
	Max. :244.00	Max. :50.81	Max. :10.000	NA	NA	NA	NA	Max. :6.00

VII. Including Plots

You can also embed plots, for example:

library(ggplot2)
p<-ggplot(data=tips,aes(smoker,fill=time))
p + geom_bar(width=0.5)

Note that the echo = FALSE parameter can be added to the code chunk to prevent printing of the R code that generated the plot. - Add bibliographies (Xie, Dervieux, and Riederer 2020). - Add bibliographies: R Core Team (2016).
