Jim, thanks so much, that's right on. Patrick, thanks to you too, but yours is not the same as what I asked: > z <- c(3,4,5,4) > names(z)<- c("a","b","c","b") > z[f] b c 4 5 Yours returns the actual values in z, not the indexes in z, i.e., not [1] 2 3 ______________________________________________ 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.
