Resources

The best resources on your journey of developing R packages are, of course, the two editions of R Packages:

• R Packages, ed 1
• R Packages, ed 2

If you're submitting to CRAN, you'll also want to keep a few extra resources handy:

• Writing R Extensions
• Preparing your package for a CRAN submission Checklist

For generally improving your code writing and debugging skills, we recommend:

• Advanced R, ed. 2
• What They Forgot to Teach You About R
• Code Smells and Feels
• The Tidyverse Styleguide
