    James> I've tried, like you suggested:

    James> un_classi <- unname(classi)

    James> but nothing changed. By typing, for instance:

    James> un_classi[[1]]

"of course" -- I just chimed in with Christian who proposed as.vector(.)
Since your 'classi' is a list with named vector as components,
you'd need something like

  un_classi <- lapply(classi, unname)

I'm sorry to have added more confusion.
OTOH, really, I think you should learn a bit more about basic
manipulation of R objects and study something like
"An Introduction to R".

    James> I still obtained twice the values. But, if I type:

    James> un_classe_01 <- unname(classi[[1]])

    James> the un_classe_01 is an unnamed vector.

(exactly, since it works on the *component* of a list)
