In the following code: > y <- 1 > niceplot( x=y )
Do you want "x", "y", or 1? 1 is just the value, which you had already. If you want "y" then the deparse(substitute()) approach gives that to you as others have said. But if you want "x", then you want to look at the names of the dots list, e.g.: > tmp <- function(...) print(names(list(...))) > tmp(x=1, y=2) [1] "x" "y" If you want something else, then a better description/example may help. -- Gregory (Greg) L.
