I'm stuck on how best to of find the distance between ordered integers (presented below as a birthday problem). Given the vector x, how do I most efficiently generate the vector x[i+1] - x[i]? Thanks. --Dale
For example... set.seed(555) x <- sample(1:365, 10, replace=TRUE) x <- sort(x) x x[i+1]-x[i] --- --------------- 14 14 0 75 61 136 61 197 61 236 39 253 17 310 57 323 13 355 32 ______________________________________________ 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.
