r - 如何按升序对r中数据框的所有列进行排序？

Question

我有一个包含 348 个数字列的数据框，我想将所有这些列按升序排列。 这个怎么做？ 我尝试了一些按升序对第一列进行排序的代码。我希望它们全部按升序排列。 示例:

a1 = runif(n = 50, min = 0.1, max = 120)
a2 = runif(n = 50, min = 5, max = 151)
a3 = runif(n = 50, min = 1, max = 100)
a4 = runif(n = 50, min = 6, max = 180)
a5 = runif(n = 50, min = 6, max = 183)
a6 = runif(n = 50, min = 6, max = 254)

df = data.frame(a1,a2,a3,a4,a5,a6)
df

df2 = df[with(df, order(a1,a2,a3,a4,a5,a6)), ]
head(df2)

df2 第一列按升序排列，但我想要全部(a1:a6 按升序排列)

Answer 1

library(tidyverse)

df %>% 
  mutate(across(everything(), sort))

# A tibble: 50 x 6
      a1    a2    a3    a4    a5    a6
   <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
 1  2.30  5.31  3.28  8.25  8.62  11.2
 2  3.39 15.6   3.70 16.4  21.0   12.7
 3  7.11 24.3   8.29 17.9  22.1   17.4
 4 10.8  24.3   9.09 25.3  25.8   22.0
 5 11.9  40.2   9.86 25.4  28.7   24.3
 6 13.7  40.6  11.3  25.7  31.3   37.1
 7 21.4  41.6  12.3  29.6  39.1   38.1
 8 27.1  56.3  12.8  39.3  40.5   45.5
 9 28.7  60.1  14.3  39.8  46.2   63.8
10 29.1  62.1  15.4  50.2  46.8   72.8
# ... with 40 more rows
# i Use `print(n = ...)` to see more rows
