[R] Problem of vocabulary : retrieve element of a list of a list

[Ptit_Bleu]

In fact I read "R pour les debutants" by Emmanuel Paradis but I didn't find
the solution.
Then I looked for on R-Help with no result.

Again I do aplologize for this silly question and I thank you for the
solution (second one).
