It's not clear to me which vector you wish to get the minimum for, but the basic premise would be along the lines of: > x [1] 1 0 1 2 3 3 4 5 5 5 6 7 8 8 9 9 10 10 > min(x[which(x > 0)]) [1] 1 or > min(which(diff(sort(x)) > 0)) [1] 1 See ?which HTH, Marc Schwartz ______________________________________________ R-help@stat.math.ethz.ch 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.
