Welcome to an introductory R course for natural scientists

One Code To Rule Them All

This page was originally built to act as an introduction to R and R studio. What it has become is that, plus a little extra. This page will be updated as new information/ lessons are requested. The link will not change, so no trouble.

We suggest starting from the beginning (even if you have used R before) and working through each section. When appropriate, previous sections will be referenced, sometimes linked, and we encourage you to use previous sections when needed. Along with this, there are snippets of code which we encourage you to give a burn and copy each into your script.

If you have any suggestions or concerns, please email me at JaredAdam@psu.edu.
