Filtering and plotting

Histogram of air time of all flights

flights %>%
  ggplot() +
  geom_histogram(
    aes(x = air_time),
    na.rm = TRUE,
    binwidth = 15
  )

flights %>%
  filter(dest != "HNL") %>%
  ggplot() +
  geom_histogram(
    aes(x = air_time),
    na.rm = TRUE,
    binwidth = 15
  )

flights %>%
  filter(dest != "HNL") %>%
  filter(between(air_time, 400, 500)) %>%
  ggplot() +
  geom_histogram(
    aes(x = air_time),
    na.rm = TRUE,
    binwidth = 10
  )
