Download and install RStudio. RStudio is an interface which facilitates coding in R. We recommend RStudio Desktop.
Download and install R Markdown. R Markdown is an authoring framework in which you can combine your code and your comments into a report.
When you have finished installing R and RStudio you can install R Markdown: Open RStudio and go to the Console (the lower left window in RStudio). Then type the following line, and run it by pressing Enter.
Download and install LaTeX. LaTeX is a typesetting system which helps you write mathematical formulas and other technical documents. It is also needed to convert your report into a PDF.
