RStudio is an integrated development environment (IDE) for the R programming language, developed by Posit (formerly RStudio Inc.). It provides a powerful interface combining code editing, console output, visualization, debugging, and workspace management in a unified environment. RStudio has become the de facto standard for R development, offering both desktop and server versions that streamline data analysis workflows. Understanding RStudio's interface, keyboard shortcuts, and integrated tools transforms how efficiently you write, test, and deploy R code — whether you're doing exploratory analysis, building packages, or creating reproducible reports with R Markdown and Quarto.
