[R] apply a function to several lists' components

Dear R-user
I have 100 lists.
Each list has several components.

For example,


[1] 1 2

[1] 3 4

[1] 5

There are data1, data2,...., data100. All lists have the same number and the same name of components.

Is there any function I can use for applying to only a specific component across 100 lists?
(e.g., taking mean of $c acorss 100 lists) or do I need to write my own function for that?

Thank you.
