I have a vector consisting of zeroes and ones, e.g. 101001. I would like to pick a random element from this vector equal to one. In the example above, that means that only elements 1, 3, or 6 can be chosen.
Is there a simple and fast way to do that? (my vector of zeroes and ones is very large) Thank you. --------------------------------------------------------- Oleg Smirnov Assistant Professor of Political Science Stony Brook University [[alternative HTML version deleted]] ______________________________________________ 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.
