Hello,
how can I return the name of a variable, say "a$b", from a function?
Use deparse(substitute(x)), not just substitute(x). By the way, to be
picky, a$b is not the name of a variable. It is an expression that
extracts the b element of a.
Duncan Murdoch
fun <- function(x){
return(substitute(x));
}
a <- data.frame(b=1:10);
fun(a$b)
... returns a$b, but this is a type language, thus I can't use it as a
character string, can I? How?
Thanks for help,
Sören
