R Intro I: Getting Started

• Open RStudio (or RGui)
• Try typing a simple mathematical expression (e.g. 1+2 ) in the console and press enter. The code is run immediately.
  • You can see the code you ran in the console, but it cannot be edited. You can however go through the latest commands run by pushing the up key on your keyboard, edit them, and run them again. If you run a lot of code this will be messy, and the code is also deleted when you quit RStudio.
