Follow the documentation ....

This is not the list for discussing compiled code (see the posting 
guide), nor have you told us what you tried.  But in fact there is only 
one way to do this, and ?.C and 'Writing R Extensions' explain it to you.

I have no idea why you would have 'a list of numbers of differing 
lengths'.  First, what is the length of a number?  Second, why not store 
numbers in numeric vectors?  An example (as required by the posting 
guide) would have helped compensate for an imprecise description.
