Text

Hi everybody! This is a RMarkdown document. You can do italics and bold, and include a links.

R code

values <- rnorm(5)
values 

# 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")

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