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

[Ian Fiske]

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
