r - 如何使用ggplot将两个r块合并在一起

Question

我有两个 r 块可以制作两个图表，但我想将它们保存在两个图表中，但将它们放入一个 r 块中，我该怎么做

accidents %>%
  filter(day_of_week != c("Sunday", "Saturday")) %>%
  ggplot(mapping = aes(x = time, fill=severity)) +
  geom_density(adjust = 2, alpha = 0.5) +
  labs(
    x = "time",
    y = "Density",
    title = "accidents in weekdays"
  )

accidents %>%
  filter(day_of_week == c("Sunday", "Saturday")) %>%
  ggplot(mapping = aes(x = time, fill=severity)) +
  geom_density(adjust = 2, alpha = 0.5) +
  labs(
    x = "time",
    y = "Density",
    title = "accidents in weekends"
  )
