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. R code chunks look like this:
# This is a comment line, which we will often use as a question prompt.
# Do not change the name of the chunk because it is used when grading.
note <- "This is a line of R code that sets a variable to a value"
note # This line will print the value to the knitted document.## [1] "This is a line of R code that sets a variable to a value"
