How it works

In the editor, you should type R code to solve the exercises. When you submit your code, every line of code is interpreted and executed by R and you get a message whether or not your code was correct. The output of your R code is shown in the console.

R makes use of the # sign to add comments, so that you and others can understand what the R code is about. Just like Twitter! Comments are not run as R code, so they will not influence your result. For example, Calculate 3 + 4 in the editor is a comment.

You can also execute R commands straight in the console. This is a good way to experiment with R code, as your submission is not checked for correctness.

  • In the editor there is already some sample code. Can you see which lines are actual R code and which are comments?
  • Add a line of code that calculates the sum of 6 and 12, and submit your code.
