Will y[order(match(y,x))] [1] 9 8 11 2 1 do? Regards Søren

Ideally the solution must be efficient in terms of timing as I'm dealing with *very* long vectors. x <- c(7, 6, 5, 9, 4, 14, 8, 12, 10, 11, 2, 13, 3, 1) y <- c(1, 2, 9, 8, 11) desired.result <- c(9, 8, 11, 2, 1) Thanks, Lars. ______________________________________________ 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. ______________________________________________ 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.
