Thanks, rowen. Let’s cover a few quick housekeeping items
before we begin our first lesson. First of all, you should
know that when you see ‘…’, that means you should press
Enter when you are done reading and ready to continue.

… <– That’s your cue to press Enter to continue

Also, when you see ‘ANSWER:’, the R prompt (>), or when you
are asked to select from a list, that means it’s your turn
to enter a response, then press Enter to continue.

Select 1, 2, or 3 and press Enter

1: Continue. 2: Proceed. 3: Let’s get going!

Selection: 1

When you are at the R prompt (>):
– Typing skip() allows you to skip the current question.
– Typing play() lets you experiment with R on your own;
swirl will ignore what you do…
– UNTIL you type nxt() which will regain swirl’s attention.
– Typing bye() causes swirl to exit. Your progress will be
saved.
– Typing main() returns you to swirl’s main menu.
– Typing info() displays these options again.

Let’s get started!
