  • Use fct_reorder() in the forcats package to reorder the country factor variable by weekly working hours in the year 2006.
    • To do that, specify the correct summary function as the third argument of fct_reorder. It should arrange the country factor levels by the last element in the working_hours variable.
  • In order to do the above, you first need to arrange() the data set by year – so 1996 is always first in each country group and 2006 is always last.
