I don't know if you mean this:

f <- function(x,...,FUN){
        y <- ave(x,...,FUN)

You can now use f() in the same way, like ave().

Or you can get rid of the names calling e.g.:

Pox2 <- structure(data.frame(ave(lsk0t50$Pox2,
lsk0t50$ProfN,Fun=is.na(lsk0t50$Pox2))), names="lsk0t50")

Why do you want a single numeric vector to be a data.frame anyway?

Best regards,
