חבילה מהרצאה של יונתן רוזנבלט מהמפגש האחרון

[Jonathan Schwartz]

מישהו יודע מה החבילות שצריך בשביל הקוד הבא:

hourly_delay <- flights %>% 

  filter(!is.na(dep_delay)) %>% 

  group_by(date, hour) %>% 

  summarise( 

    delay = mean(dep_delay), 

    n = n() ) %>% 

  filter(n > 10)

חוץ מ magrittr?
