d<-data.frame(a=1:3, b=3:5,c=9:11) > d a b c 1 1 3 9 2 2 4 10 3 3 5 11 > d[identical(d[c("b","c")],c(4,10)),] [1] a b c <0 rows> (or 0-length row.names) [[alternative HTML version deleted]] ______________________________________________ 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.
