Hi,
set.seed(42)
mat1 <- matrix(sample(40,5*3,replace=TRUE),ncol=3)
mat2 <- apply(mat1,1,sort,decreasing=TRUE)
mat2[1,]- mat2[2,]
A.K.
Thank you.
And if I have a lot of rows? How can I apply this for row?

Hi,
I need some help in a simple thing....
If I have 3 classes like 56 98 15, I need do max1-max2
where the max 1 is the maximun (98) and the max2 is the second maximun
(56)...
How can I do this in R? To obtain the max I used apply(data, 1, max),
but...and the other?
Thanks
