R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

# generate 50 observations
x <- seq(1,20,length=50)
epsilon <- rnorm(50, 9)
y <- 3 + .1*x + epsilon

Including Plots

You can also embed plots, for example:

plot(x,y)
quintic <- lm(y ~ x + I(x^2) + I(x^3) + I(x^4) + I(x^5) )
lines(x,quintic$fitted.values, col="blue")

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
