I am following this example, the server.R, file is here.
I plan to do a similar filter, but am lost as to what %>% does.
 # Apply filters
    m <- all_movies %>%
      filter(
        Reviews >= reviews,
        Oscars >= oscars,
        Year >= minyear,
        Year <= maxyear,
        BoxOffice >= minboxoffice,
        BoxOffice <= maxboxoffice
      ) %>%
      arrange(Oscars)
