I recently wrote a book called Applied Statistics with R: A Practical Guide for the Life Sciences. If you are interested, it can be ordered from Oxford University Press here. I truly hope you find it useful. All of the companion materials — the dataset needed to work through the examples in the book and answers to the problems at the end of each chapter — can be found on Oxford’s companion website to the book or on the GitHub page I created for the book. You can also find pdfs of sample answers for each chapter below. 

If you already have the book and have a question or have found a typo or mistake or something, please feel free to email me at jutouchon-at-vassar-dot-edu.

You can download R here. If you would also like to use the program RStudio, you can download it for free here. At Vassar we have a web server version of RStudio which you can access and login to with your Vassar OneLogin password (email Karly Andreassen in ACS to obtain an account).

Below are some tutorial videos I made for Vassar’s Intro Biology course a few years back that demonstrate some extremely simple but important tasks, like importing a dataset into R and such. Maybe if you are stuck at the very beginning of everything they can help you!
