Dear All, (my apologies if it got posted twice, it seems it didn't get through)
I cannot find a solution to the following problem although I suppose this is a classic. I have a vector V of X=length(V) values comprised between 1 and N. I would like to get random samples of X values also comprised between 1 and N, but the important point is: * I would like to keep the same distribution of distances between the original X values * For example let's say N=10 and I have V = c(3,4,5,6) then the random values could be 1,2,3,4 or 2,3,4,5 or 3,4,5,6, or 4,5,6,7 etc.. so that the distribution of distances (3 <-> 4, 3 <->5, 3 <-> 6, 4 <-> 5, 4 <-> 6 etc ...) is kept constant. I couldn't find a package that help me with this, but it looks like it should be a classic problem so there should be something! Many thanks in advance for any help or hint you could provide, All the best, Emmanuel ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
