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.

Here is the text from the assignment: ## This is a markdown file

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:

summary(cars)

You can also embed plots, for example:

plot(cars)

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