Re: [R] Re turning variable names with variables (in a function)

You want to set the "names" attribute of your results vector. You can do this with the names() function (see ?names). Specifically, you might use something like this:     

    results <- c(se, upper, lower, cv)
    names(results) <- c("se", "upper", "lower", "cv")

Good luck,
Ian
