be sorted by row in ascending/descending order?
Given this matrix:
57 91 31 61 16
84 3 99 85 47
21 6 57 91 31
61 16 84 3 99
I want to end with this:
21 6 57 91 31
57 91 31 61 16
61 16 84 3 99
84 3 99 85 47
The 'order' of the sort is: 3 1 4 2
Also, what R expression will give me the 'order'?
Thanks.
