Understanding R and RStudio 🤔
R is a powerful programming language used for statistical computing and graphics. It’s widely used among statisticians and data miners for developing statistical software and data analysis. RStudio, on the other hand, is an integrated development environment (IDE) for R. It makes using R easier by providing a user-friendly interface and additional features.
Think of R as the engine of a car and RStudio as the dashboard. You need both to drive smoothly! 🚗
Key Terminology
- R: A programming language for statistical computing.
- RStudio: An IDE that provides tools to make R easier to use.
- IDE: Integrated Development Environment, a software application that provides comprehensive facilities to programmers for software development.
