GeeksforGeeks offers R programming articles with embedded practice programs. Though not interactive, they serve as a reference with code snippets and exercises that learners can run locally.

Useful for those who prefer reading with accompanying practice.

10. Programiz R Guide (Beta)

Programiz has launched a basic R programming tutorial series, designed with structured walkthroughs. Though still in early stages, it provides practice code blocks embedded within learning content.

It also provides an online compiler for you to practice R programming from scratch. Ideal for learners who want beginner-friendly content in a familiar style.

Tips to Practice R Programming Effectively

• Start with Data Basics: Focus first on vectors, data frames, and basic plots — these are core to working with R.
• Practice with Real Datasets: Use platforms that include real-world datasets for tasks like cleaning, filtering, and analysis.
• Try Mini Projects: Build simple projects like weather dashboards or stock trend analysis — they help apply your skills in context.
• Be Consistent: Practice 30–45 minutes daily instead of long, occasional sessions. It helps retain concepts better.
• Use Community Forums: Join R-related groups or forums to ask questions and see how others solve similar problems.

Final Words

With so many beginner-focused platforms available, learning R programming is more accessible than ever. Websites like Placement Preparation, GUVI, DataCamp, and R-exercises offer hands-on tasks, feedback loops, and step-by-step challenges to improve your coding confidence.

Whether you’re preparing for data science interviews, working on research, or just exploring analytics, these tools give you the space to practice and grow. We’ll keep updating this article as new and better tools become available for learners like you.
