Well, 'list' must be pretty close! The main difference would be
that in C the structure type would be declared first, and then
applied to create an object with that structure, whereas an R
lists are created straight off. If you want to set up a generic
list type for a certain purpose, you would wrap its definition
in a function.

Another difference is that R lacks the "pointer" type, so that
R's "mylist$component" is the equivalent of C's "mylist.component";
I don't think you can do the equivalent in R of C's "mylist->component"
(though I'm likely to be wrong about that, and to be promptly corrected)!

Hopingb this helps,
