Hello,
I have a matrix results with dimension 1x9 double matrix
XLB XLE XLF XLI
1 53.3089 55.77923 37.64458 83.08646
I'm trying to order this matrix
> print(order(results))
[1] 3 1 2 4
how can the function order return the columnname XLF XLB XLE XLI instead
of 3 1 2 4
any idea ?
Thank you in advance

With similar data, since you didn't include reproducible example of your own:> results <- matrix(c(53, 55, 37, 83), nrow=1) > colnames(results) <- letters[1:4] > resultsa b c d [1,] 53 55 37 83> order(results)[1] 3 1 2 4> colnames(results)[order(results)][1] "c" "a" "b" "d" On Fri, Dec 2, 2011 at 2:45 PM, Martin Bauer <Bauermartin at gmx.at> wrote:> Hello, > > > I have a matrix results with dimension 1x9 double matrix > > ? ? ? ?
