Your first R script
Welcome! In the script to the right you will type R code to solve the exercises. When you hit the Submit Answer button, every line of code in the script is executed by R and you get a message that indicates whether or not your code was correct. The output of your submission is shown in the R console.
You can also execute code directly in the R Console. When you type in the console, your submission will not be checked for correctness! Try, for example, to type in 3 + 4 and hit Enter. R should return [1] 7.
