IDEs

There exist several Integrated Development Environments (IDEs) for R. Here are some of them:

• rstudio
• vs code
• emacs

rstudio has been designed to work around R. It is free and open-source. It is available for Windows, Mac, and Linux. It works very well git. Quarto has been designed and developed by the same team.

vs code is a general-purpose IDE. It works very well with git. It is very versatile and can be used for many programming languages. It is endowed with a large number of extensions for R, Python, SQL, and Quarto. It integrates very well with git. It is promoted by github just as copilot

emacs is a classical and powerful general-purpose editor that can be turned into an IDE. It is available for Windows, Mac, and Linux. It also works very well with git. Extension ESS (Emacs Speaks Statistics) is available for R.

In the course, we will use rstudio and vs code.
