Hi, I want to sort my matrix according to (any) selected column. For example
given matrix:
> x
[,1] [,2] [,3]
[1,] 3 4 7
[2,] 2 5 8
[3,] 1 6 9
I want to sort the first column in ascending order and make the other
columns follow the 'new order' like:
> x1
[,1] [,2] [,3]
[1,] 1 6 9
[2,] 2 5 8
[3,] 3 4 7
thank in advance for help.
best
