Top right includes history and variables you have created in your current session.
Bottom left is the R console you can run commands directly here after the cursor >.
Bottom right is the file explorer, plotting screen, packages lists and help files.

Start a new script

  • Open up a new script by selecting from the top left icon for New File



  • Select R Script.
  • A script is a record of the analyses we are working on, and typically will run again.
  • Annotations in the script, called comments, aid users in understanding the script and are denoted by # at the beginning of each line.  Comments do not run in the console.
  • It is good practice to put a description at the top of your script: what it is for, author, date, dataset etc used.  This is will serve as a reminder as to what the script is for in the future.
  • Complete a description of your script and then save it as a .R file in your folder by clicking the save icon ( a blue disk).
