## Summary
In this chapter, you've learned how to use readr to load rectangular flat files from disk into R.
You've learned how csv files work, some of the problems you might encounter, and how to overcome them.
We'll come to data import a few times in this book: @sec-import-databases will show you how to load data from databases, @sec-import-spreadsheets from Excel and googlesheets, @sec-import-rectangling from JSON, and @sec-import-scraping from websites.
Now that you're writing a substantial amount of R code, it's time to learn more about organizing your code into files and directories.
In the next chapter, you'll learn all about the advantages of scripts and projects, and some of the many tools that they provide to make your life easier.
