ABSTRACT
When conducting research your end product is usually a Word Document or a PDF which reports on the research you've done, often including several graphs or tables. In many cases people do the data work in R, producing the graphs or numbers for the table, and then write up the results in Word or LaTeX. When you're making a report for a general audience you generally only want to show the output (e.g. a graph or table), not the code that you used. At early stages in writing the report or when you're collaborating with someone who wants to see your code, it is useful to include the code in the R Markdown output. You can also include R code directly in the text of your document and it will return the output of that code.
