r - Rで行列の列を個別にソートする方法はありますか?

Question

私はRの初心者なので、ここで本当に助けが必要です。各列を個別に並べ替えたいだけです。どんな助けでも大歓迎です！

 > mat <- matrix(c(45,34,1,3,4325,23,1,2,5,7,3,4,32,734,2),ncol=3)
 > mat
      [,1] [,2] [,3]
 [1,]   45   23    3
 [2,]   34    1    4
 [3,]    1    2   32
 [4,]    3    5  734
 [5,] 4325    7    2

に

      [,1] [,2] [,3]
 [1,]    1    1    2
 [2,]    3    2    3
 [3,]   34    5    4
 [4,]   45    7   32
 [5,] 4325    23 734

Answer 1

はいあります！

apply(mat, 2, sort)
     [,1] [,2] [,3]
[1,]    1    1    2
[2,]    3    2    3
[3,]   34    5    4
[4,]   45    7   32
[5,] 4325   23  734
