Start a new script

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).
