• For the following loop, please answer the questions

  arbitrary_vec <- c(-1, 0, 1, -1)
  for(i in arbitrary_vec){
      print(i)
  }
  

  • What is the final value for i?
  • How many times have i been defined?
  • If I re-wrote the code above by replacing i with element, does the loop behave differently not defining a variable i?
