plotly 라이브러리를 불러옵니다
library(plotly)
ggplot 객체를 ggplotly()에 넣어 plotly 객체를 만듭니다
ggplotly(<ggplot object>)
bubble로 저장합니다price와 availability_365의 관계를 보여줍니다room_type별로 색을 다르게 합니다bubble <- listings %>%group_by(room_type, neighbourhood) %>% summarise(avg_price = mean(price, na.rm=TRUE), avg_availability = mean(availability_365, na.rm=TRUE),Count = n(), .groups = "drop") %>%ggplot(aes(x = avg_price, y = avg_availability,color = room_type,size = Count)) +geom_point() +labs(x = "Average price", y = "Average availability", color = "Room type") + theme_classic()
bubble을 ggplotly()로 감쌉니다ggplotly(bubble)

일부 플롯은 올바르게 변환되지 않습니다
가로 방향의 상자그림을 만듭니다
room_type별 availability_365 분포를 설명합니다ggplotly() 변환이 작동하지 않습니다boxH <- listings %>%ggplot(aes(x = availability_365, y=room_type)) +geom_boxplot() +labs(x="Availbility (out of 365 days)", y="Room type") + theme_classic()
ggplotly(boxH)
aes()에서 x와 y를 바꿉니다boxV <- listings %>%ggplot(aes(y = availability_365, x=room_type)) + geom_boxplot() + labs(y="Availbility (out of 365 days)", x="Room type") + theme_classic()
ggplotly(boxV)

coord_flip()을 추가합니다facet_wrap()도 사용할 수 있습니다ggplotly(boxV + coord_flip())
ggplotly(boxV + coord_flip() +
facet_wrap(~neighbourhood))
