Nombre de cas de covid dans les commissions scolaires

This is a quick blog post to try and figure out which school boards are the “hottest zones” for covid. In this blog post, I will do the following: - get the shapefiles for both the school boards (commission scolaires, or CS) and the smallest possible health districts (réseau local de santé, or RLS) - find the intersection between school boards and RLS using sf::st_intersection() - find the population of each intersection using cancensus::get_census() and tongfen::tongfen_estimate() - assign the number of cases in each health district (RLS) to each intersection proportionnaly to the population using tongfen::proportional_reaggregate() - sum the number of cases for each school board (commissions scolaires).
