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. For assignments, I will ask you for the Rmd file and the knitted HTML, along with any other files that are external to the Rmd file and loaded; this allows me to execute your code if need be.
You can embed an R code chunk like this:
# Create an object called 'values' that consists of the integers from 1 to 1000
values = seq(1,1000)
# Set the seed for a random number generator and sample (size of 10) from the object 'values'
set.seed(432432)
s1 = sample(values, size = 10, replace = FALSE)
s1 [1] 129 910 238 57 715 650 140 337 690 684# Create an object called 'normal.values' that come from a Normal Distribution
# with a mean of 100 and standard deviation of 10 (sample size of 50)
set.seed(4324321)
normal.values = rnorm(50, mean = 100, sd = 10)

Note that the echo = FALSE argument was added to the code chunk so that the code text is not printed in the output file.
