對于資料集df（資料貼在本題末尾），我嘗試使用gg_season()并gghighlight(year >= 2020)突出顯示 2020 年后的行。
但是輸出顯然不如預期，我該如何修改才能year >= 2020達到正確的繪圖效果？謝謝。
library(tidyverse)
library(lubridate)
library(feasts)
library(tsibble)
library(gghighlight)
df %>%
mutate(date = as.Date(date, origin = "1899-12-30")) %>%
mutate(year=year(date)) %>%
pivot_longer(`food_index`:`energy_index`) %>%
mutate(date=yearmonth(date)) %>%
as_tsibble(index=date, key=name) %>%
gg_season(value, alpha=1)
geom_line(size=0.8, alpha=0.8)
geom_point(size=2, alpha=1)
gghighlight(year >= 2020)
