You will need to install two pieces of software on your computer for these lessons: R and RStudio. Installation for R may vary by your operating system; follow the instructions below for your OS. Some lessons also include a small amount of work in a spreadsheet environment like Microsoft Excel® or LibreOffice Calc. If you do not have spreadsheet software, you can download LibreOffice Calc for free (either the "fresh" or "still" versions will work).

If you have questions about installation, or run into problems, please feel free to e-mail me at jcoliver@email.arizona.edu.
