column sorting a matrix with indices returned
Hi,
I'm trying to translate some Matlab code to R and I'm trying to
implement the behavior of Matlab's sort() which when applied to a matrix
will sort the columns returning the column sorted matrix as well as a
matrix of permuted indices.
Doing:
> x <- matrix(c(3,4,2,6,3,4,8,7,5), nr=3)
> x
[,1] [,2] [,3]
[1,] 3 6 8
[2,] 4 3 7
[3,] 2 4 5
