I have 2 vectors A and B. For each element of B I'd like to find the index of the next higher or equal element in A. And I'd like to store it effectiv. E.g.: A <- c(1,3,7,8,10) B <- c(5,8)
result: 3, 4 I have a possibility but for long vectors it works not very effectiv: ans <- sapply(B, function(x) which.max(A[A < x]) ) as.integer(ans + 1) Is there anyone how has a better idea? Thank you for your help, Thomas. -- ______________________________________________ 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.
