| Hi! I see that you have some variables saved in your
| workspace. To keep things running smoothly, I
| recommend you clean up before starting swirl.

| Type ls() to see a list of the variables in your
| workspace. Then, type rm(list=ls()) to clear your
| workspace.

| Type swirl() when you are ready to begin.
