which(data==max(data),arr.ind=TRUE)
gives you the indices of the largest element.
which(data==data[order(data)[2]],arr.ind=TRUE)
the indices of the second largest.

hi All,
I have a matrix Ufi (x by y)
1 2 3 4 5
1 0 0 0 0 3
2 0 0 0 9 0
3 0 2 0 0 3
4 0 0 1 0 0
5 0 1 0 0 0
And I need the x and y "coordinates" of those cells with maximum values:
First:
x=4; y=2 (Value=9)
Second:
x=5; y=3 (value=3)
Any help?
THANKS!
Nic
