'$' doesn't evaluate its argument. You want mylist[[entrylabel]].

R lists do have names, but they are not hashes. You can have
duplicate names in different positions in a list.
You can get at list elements by name using $name and [[name]], but the
argument to $ has to be the actual name, not a var containing the
name.
You can also access elements by number using [[i]]
