假设我有以下名为data的tibble Dataframe ：

library(tibble)

data <- tribble(
    ~"ID", ~"some factor", ~"some other factor", 
    1L, "low", "high",
    2L, "very high", "low",
    3L, "very low", "low",
    4L, "high", "very high",
    5L, "very low", "very low"
)

我使用forcats中的fct()函数来相应地转换我的两个因子变量：

library(dplyr)
library(forcats)

data <- data %>%
        mutate(across(starts_with("some"), fct))

这就给了我：

# A tibble: 5 × 3
     ID `some factor` `some other factor`
  <int> <fct>         <fct>              
1     1 low           high               
2     2 very high     low                
3     3 very low      low                
4     4 high          very high          
5     5 very low      very low

然而，当我这样调用fct时，我不清楚如何指定这个有序变量的水平，我希望的顺序是：

order <- c("very low", "low", "high", "very high")

**如何使用dplyr的函数集？**我们的目标是使ggplot2可视化遵守这种顺序。
