[R] Re order matrix columns

Hi, I have found the following thread to reorder a data.frame. I would like to do same regarding a matrix: https://stat.ethz.ch/pipermail/r-help/2008-February/154138.html I achieved this with a for loop and cbind but I think using 'is.element' is much more appropriate. Can anyone help? Cheers
