Good day, What is a fast and efficient way to calculate the minimum absolute difference between two vectors of numbers? The two vectors have unequal length. I would also like to know the index of the first vector and the second vector which results in the minimum absolute difference. For example:
x <- rpois(500, 100) y <- rpois(300, 30) Is there a much faster way than a nested for loop without resorting to Rcpp? -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
