Olympic medals per continent

You want to compare Olympic performance of athletes per continent over time, both on the winter and summer Olympics. You've been given a dataset medal_df with the average number of medals won per participant of each continent since 1928. You'll complete this data to introduce zero values for years where a continent did not win any medals.

Instructions

  • Complete the dataset so that each continent has a medals_per_participant value at each Olympic event. Missing values should be filled with zeros.
  • Nest the season and year variables using the nesting() function, since the summer and winter Olympics don't occur in the same years.
  • Use ggplot() to create a line plot with the medals_per_participant per year, color the plot by continent.
