Hi,
Here are part of my data,
> pr16.5
origin dest ldco time.slot distortion
1 1 1 1 1 4.3
2 1 1 1 2 4.7
3 1 1 1 3 5.6
4 1 1 1 4 7.7
5 1 1 2 1 6.8
6 1 1 2 2 7.6
7 1 1 2 3 9.2
8 1 1 2 4 10.7
9 1 1 3 1 2.3
10 1 1 3 2 2.2
11 1 1 3 3 2.6
12 1 1 3 4 4.3
13 1 2 1 1 3.2
14 1 2 1 2 5.4
15 1 2 1 3 4.9
16 1 2 1 4 10.7
17 1 2 2 1 5.6
18 1 2 2 2 8.0
19 1 2 2 3 7.7
20 1 2 2 4 13.1
21 1 2 3 1 0.3
22 1 2 3 2 2.3
23 1 2 3 3 3.0
24 1 2 3 4 8.2
I want to reorder the matrix according to variable time.slot, i.e.
time slot<- c(1,1,1,1,1,...,2,2,2,2....,3,3,3,3....,4,4,4,4,...)
Is there any way like a command or construct a function?
Thanks!
