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
.Rfile in your folder by clicking the save icon ( a blue disk).
