One of the great advantages of R over point-and-click analysis software is that you can save your work as scripts. You can edit and save these scripts using a text editor. The material in this book was developed using the interactive integrated development environment (IDE) RStudio[10]. RStudio includes an editor with many R specific features, a console to execute your code, and other useful panes, including one to show figures.

Most web-based R consoles also provide a pane to edit scripts, but not all permit you to save the scripts for later use.
