Hi! This is my document to R Markdown. I can do italics and bold, and I will include a link of my favorite singer [link]{https://www.youtube.com/results?search_query=justin+bieber+daisies}

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

  g <- ggplot(mpg, aes(cty, hwy))
