R Markdown Practice

Introduction

Hi everybody. This is an R Markdown document. You can do italics and bold, and include a link

R Code

values <- rnorm(5)
values

We can also use echo to show or not show the code and results/eval to show or not show the output.

More text tools

Subheadings

Unordered lists:

• First Item

• Second Item

Ordered lists:

1. First

2. Second

We can insert an image like this:

We can add citations¹

We can use math mode \(\alpha, \beta\) and so on.

Finally, we can make nice tables.

penguins_sm <- head(penguins)
kable(penguins_sm)

species	island	bill_length_mm	bill_depth_mm	flipper_length_mm	body_mass_g	sex	year
Adelie	Torgersen	39.1	18.7	181	3750	male	2007
Adelie	Torgersen	39.5	17.4	186	3800	female	2007
Adelie	Torgersen	40.3	18.0	195	3250	female	2007
Adelie	Torgersen	NA	NA	NA	NA	NA	2007
Adelie	Torgersen	36.7	19.3	193	3450	female	2007
Adelie	Torgersen	39.3	20.6	190	3650	male	2007

Including Graph

# load package and data
library(ggplot2)
data(mpg, package="ggplot2")    # mpg <- read.csv("http://goo.gl/uEeRGu")

# Scatterplot
theme_set(theme_bw())  # pre-set the bw theme.
    g <- ggplot(mpg, aes(cty, hwy))
    g + geom_jitter(width = .5, size=1) +
      labs(subtitle="mpg: city vs highway mileage", 
           y="hwy", 
           x="cty", 
           title="Jittered Points")
