Emacs vs RStudio: What are the differences?

1. User Interface: One key difference between Emacs and RStudio is their user interface. Emacs has a more minimalistic and text-based user interface, with a command line at the bottom that allows users to interact with the editor using keyboard shortcuts. On the other hand, RStudio offers a more graphical user interface, with menus, buttons, and a file navigator that makes it easier for users to navigate and interact with the editor using both keyboard and mouse.
2. Customizability: Emacs is known for its high level of customizability. It allows users to modify and extend almost every aspect of the editor's functionality, including the appearance, keybindings, and behavior. RStudio, on the other hand, has a more limited level of customizability. While users can customize certain aspects of the editor, such as the theme and keybindings, they do not have the same level of flexibility and control as Emacs users.
3. Focused on Emacs Lisp: Emacs is built around the Emacs Lisp programming language, which is used for extending and customizing the editor. This means that Emacs users can not only customize the behavior of the editor, but they can also write and execute code within the editor itself. In contrast, RStudio is specifically designed for R programming and does not have the same built-in support for writing and executing code in other languages.
4. Integrated Development Environment (IDE) Features: RStudio is primarily an integrated development environment (IDE) for R programming. It provides a range of features specifically designed for R development, such as code completion, debugging tools, and integrated documentation. Emacs, on the other hand, is a more general-purpose text editor that can be customized and extended to support a wide range of programming languages but may not have the same level of specialized features for a specific programming language.
5. Package and Environment Management: RStudio has built-in support for managing R packages and environments. It provides a package manager that allows users to easily install, update, and remove R packages, as well as tools for managing different R environments and project directories. Emacs, on the other hand, requires users to rely on external tools and packages to manage packages and environments, and does not have the same level of built-in support.
6. Learning Curve: Due to its customizability and extensibility, Emacs has a steeper learning curve compared to RStudio. Emacs requires users to learn and understand Emacs Lisp in order to fully take advantage of its customization capabilities. RStudio, on the other hand, is designed to be more user-friendly and intuitive, making it easier for users, especially those familiar with the R programming language, to get started and be productive quickly.

In Summary, Emacs provides a highly customizable and extensible text editor with a minimalistic interface, while RStudio is a more specialized integrated development environment designed specifically for R programming with a graphical user interface and a range of built-in features.
