Soviet space dogs, the flight perspective
Remember the USSR space dogs dataset1? You changed it to a long format so that for every dog in every rocket launch, there was a row. Suppose you're given this tidy dataset and are asked to answer the question, "In what percentage of flights were both dogs of the same gender?"
You'll reshape and investigate space_dogs_df to find the answer.
The dplyr package has been pre-loaded for you.
