docstrings

Remove docstrings

• If we're advocating writing packages then docstrings are only briefly useful in Series 2
• If they're used in Series 3 (in packaged functions), they cause roxygen2 to generate a warning

I'm in two minds about this - I like being able to show documentation for functions not in packages, but it's not ideal.

[soniamitchell]

I wouldn’t mind if it wasn’t for the fact that series 3, 4, and the final project are package focused.

[richardreeve]

Yes, you're probably right. Maybe we just demonstrate it at some point, but don't ask them to use it.

I think presenting multiple ways of doing something invites confusion. It's fun to learn new ways of doing things if you're already familiar with R, but as a beginner it might not be so helpful?
