About RGuides

RGuides is a free resource for R programmers and data scientists. We publish tutorials, guides, articles, and a complete reference covering the R language, the tidyverse, statistical methods, and data visualization.

What you'll find here

• Tutorials — Step-by-step series that take you from installing R to building real data analysis pipelines. Follow them in order.
• Guides — In-depth walkthroughs of specific R concepts, packages, and statistical methods. Pick the topic you need.
• Reference — Quick-lookup documentation for base functions, data types, string functions, math functions, and tidyverse verbs.
• Articles — News, deep dives, and analysis of what's happening in the R ecosystem.

Our approach

Every page on this site is written to be clear, accurate, and practical. We show real code examples that you can copy and run in RStudio or the console. We explain the why, not just the how.

R's built-in help system and CRAN documentation are thorough but can be terse. RGuides fills the gap with focused explanations, working examples, and practical guidance on when to use each function or package.

Who this is for

Whether you're writing your first R script or building complex Shiny applications, there's something here for you. Content is tagged by difficulty level — beginner, intermediate, and advanced — so you can find material at the right level.
