Colleagues, I have generated several dummy variables:
n$native0 <- 1 * (n$re=="white" & n$usborn=="yes") n$native1 <- 1 * (n$re=="afam" & n$usborn=="yes") n$native2 <- 1 * (n$re=="carib" & n$usborn=="yes") n$native3 <- 1 * (n$re=="carib" & n$usborn=="no") I would now like to combine these into a single categorical variable where the new variable would be n$native. And values of native would be 0 through 3, where n$native0 would be a 0 value on n$native, n$native1 would be a 1 value on n$native etc. Any help would be greatly appreciated. -- Mosi ______________________________________________ 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.
