Підтримати Yang Feng

I’m Yang Feng, a professor of biostatistics passionate about open education and accessible data science.

I created r02pro to help students, educators, and researchers learn R programming through clear, hands-on examples — and I’m offering the full book online for free.

If you find my work helpful, your support helps me continue creating and maintaining open educational resources like this one. Every contribution — large or small — truly makes a difference.

Thank you for being part of this learning journey! 🙌
