As this is the first set exercises in this course, it is quite easy and short. Its purpose is also to get used to this exercise format and, more importantly, to get a first feeling for working with R
and RStudio.
Note: You can find the solutions for this exercise as well as all other exercises in the solutions
folder in the repo/directory that contains the course materials. You can easily copy code from these solution files by clicking on the small blue clipboard icon in the upper right corner of the solution boxes showing the code.
For the following simple coding tasks in this first set of exercises, you can just work interactively in the Console in R
/RStudio.
Feel free to play around a bit and try a few things out.
R

tab in the RStudio interface. The object you created should now be visible there.
