Was ist der richtige R-Code, um das Diagramm zu erzeugen?

**R-Code A** 

flights %>%
  ggplot(aes(x = hour, y = dep_delay)) + 
  geom_boxplot(aes(group = hour)) + 
  geom_smooth() + 
  coord_cartesian(ylim = c(-10, 60)) + 
  scale_x_continuous(breaks = 1:24)


**R-Code B** 

flights %>%
  select(dep_delay, hour) %>% 
  ggplot(aes(x = hour, y = dep_delay)) + 
  geom_boxplot(aes(group = hour)) + 
  coord_cartesian(ylim = c(-10, 60)) + 
  scale_x_continuous(breaks = 1:24)


**R-Code C** 

flights %>%
  select(arr_delay, hour) %>% 
  ggplot(aes(x = hour, y = arr_delay)) + 
  geom_boxplot(aes(group = hour)) + 
  geom_smooth(method = 'lm') + 
  coord_cartesian(ylim = c(-10, 60))


**R-Code D** 

flights %>%
  select(dep_delay, hour) %>% 
  ggplot(aes(y = hour, x = dep_delay)) + 
  geom_boxplot(aes(group = dep_delay)) + 
  geom_smooth(method = 'lm') + 
  coord_cartesian(ylim = c(-10, 60)) + 
  scale_x_continuous(breaks = 1:24)


**R-Code E** 

flights %>%
  select(dep_delay, hour) %>% 
  ggplot(aes(x = hour, y = dep_delay)) + 
  geom_boxplot(aes(group = hour)) + 
  geom_smooth(method = 'lm') + 
  coord_cartesian(ylim = c(-10, 60)) + 
  scale_x_continuous(breaks = 1:24)

208 Solution

Der Code-Auszug E ist korrekt.
