Oh, this seemed so simple (and I'm sure the answer will be, as usual, so
thanks in advance for enlightening me). I need to sort each row of a matrix
independent of the others. For example,
> test <- matrix(c(8,7,1,2,6,5,9,4,3),nrow=3)
> test
[,1] [,2] [,3]
[1,] 8 2 9
[2,] 7 6 4
[3,] 1 5 3
I can get each row sorted well enough.
> sort(test[1,])
[1] 2 8 9
> sort(test[2,])
[1] 4 6 7
> sort(test[3,])
[1] 1 3 5
Now I just need the resulting matrix:
2 8 9
4 6 7
1 3 5
But when I try to turn this into something more automated, I only get the
last row.
> for(e in 1:3) sorted <- sort(test[e,])
> sorted
[1] 1 3 5
I've tried various incarnations of rbind around my loop, but to no avail.
I've search my books and the forums, and I'm sure there is some nifty R
function out there, but I can't seem to find it and/or apply it correctly.
Cheers,
Kev-
