Thanks. Works
A doubt.

I asked that because I have a loop that can generate objects like that or
this one


str(object)
Named num [1:2] 670 314
 - attr(*, "names")= chr [1:2] "x" "y"

To avoid using a ifelse() to calculate means of x and y, I'd like a function
that handle with this named numeric object and that list. Any chance of do
it with a single function?
