Re: [R] Ordering variables in a parallel coordinates plot
Hi Charles, Thanks for answering - you are right about the posting guide (sorry). In any case, my question wasn't on how to reorder the columns (that is simple), but on how to choose what order to put them in.

Re: [R] Ordering variables in a parallel coordinates plot
Hi Charles, You're solution is great (and is actually what my professor suggested me to do today). In the meantime I searched even more and found this article: http://davis.wpi.edu/~xmdv/docs/tr0313_osf.pdf That gives a good description of the problem and of his attempts at solving it. I started by implementing (in a very rough way) the solution of all possible combinations, but it is not relevant for more then 7 dimensions. His solution will involve a mix of your solution with a local optimum, but I don't think I will go more into solving it anytime soon (but instead, make due with your solution).
