Where this leaves us

You now have the four things the rest of the book assumes: a language, a way of asking questions of a table, a way of drawing what you found, and a folder that keeps it together.

None of it needs to be complete. Nobody remembers every argument of ggplot(), and reaching for the help page is not a sign of weakness. What matters is the movement — question, data, code, result, and back up to the question.

That is the dolphin. Let us dive.
