我是R的新手,所以我真的需要一些帮助。我只想独立地对每列进行排序。任何帮助表示赞赏!
> 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
到
[,1] [,2] [,3]
[1,] 1 1 2
[2,] 3 2 3
[3,] 34 5 4
[4,] 45 7 32
[5,] 4325 23 734

是的,有!
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
