Online Courses#

Coursera - "The Data Scientist’s Toolbox"#

This course by Johns Hopkins University is a great starting point for beginners. It introduces you to the R programming language and covers topics like data manipulation, visualization, and basic statistical analysis. The course is well-structured with video lectures, quizzes, and programming assignments.

edX - "Introduction to R Programming"#

Offered by Microsoft, this course is designed to teach you the fundamentals of R programming. You'll learn how to write R scripts, work with data frames, and create basic visualizations. The hands-on approach of this course makes it easy to apply what you learn.

Books#

"R for Data Science" by Hadley Wickham and Garrett Grolemund#

This is a comprehensive guide for anyone interested in using R for data analysis. It covers everything from data import and cleaning to advanced data visualization and modeling. The book is written in a clear and accessible style, making it suitable for beginners and experienced users alike.

"Advanced R" by Hadley Wickham#

Once you have a solid foundation in R, this book is a must-read. It delves into more advanced topics such as functionals, metaprogramming, and debugging. It helps you write more efficient and maintainable R code.

Interactive Learning Platforms#

DataCamp#

DataCamp offers a wide range of R courses, from beginner to advanced levels. The courses are interactive, with video tutorials and coding exercises. You can learn at your own pace and track your progress. DataCamp also has a community forum where you can ask questions and get help from other learners.

Codecademy#

Codecademy's R course is another great option for beginners. It uses a gamified approach to teaching, making learning fun and engaging. You'll learn the basics of R programming through interactive lessons and projects.

R Documentation#

R Help Pages#

The built-in help pages in R are an invaluable resource. You can access them by typing ?function_name in the R console. The help pages provide detailed information about functions, their arguments, and examples of how to use them.

R Manuals#

The R Project website has several manuals available for download. The "An Introduction to R" manual is a great starting point for beginners. It covers the basics of R programming, including data types, control structures, and functions.

Stack Overflow#

Stack Overflow is a popular Q&A website for programmers. You can search for R-related questions and answers on Stack Overflow. If you have a problem or a question, you can also post it on the site and get help from the community. Just make sure to search for existing answers before posting to avoid duplicates.

R Blogs and Podcasts#

R-bloggers#

R-bloggers is a website that aggregates blog posts from R users around the world. You can find articles on a wide range of topics, from beginner tutorials to advanced data analysis techniques. It's a great way to stay updated on the latest trends and best practices in R programming.
