Challenges Set 2

Instructions

Use the starwars dataset from the dplyr package (loaded already with tidyverse) to complete the below challenges. I highly recommend all of you to first get to know the starwars dataset by trying the “Get to know your data” functions covered at the beginning of the Week 2 Starter file. Good luck and have fun in completing them:

Important

If you want to add a twist.. can you complete them also using the pipe (|>)?
