In this course, we will use the programming language called R. To make the use of R more convenient, we can use RStudio. RStudio makes it convenient to write code, execute our code, see the output of the code and to have an overview of what objects (datasets, vectors, functions, etc) are loaded into our R environment. Note that R can be used without RStudio, but RStudio can not be used without R. RStudio is a means to interact with R. We need to first install R itself and subsequently RStudio. These steps will be explained in the following exercises.

It is advised to always develop your code in RStudio and once you finished the exercise, you can submit your code to Dodona in order to check if your code is correct.
