R help - Mar 2012 - Apply a loop containing a function on a list

Hi all,
I want to do this:
	
	B.list$aa= (a loop containing My.fun acting on the reults of second
function on a A.list$aa))
or, overally 		
	B.list$aa = function (A.list$aa)
B.list and A.list has many sublists aa, ab and.... Is there a way I can
apply the function and loop on all sublists of A.list and get B.list?


Thanks in advance.

Please provide a small example, you can easily create two lists to
illustrate your point. It's hard to help without that, it would require
us mocking up an example for you, and we might get it wrong.


Cheers

Without a subset of data, it is hard to come up with a solution.  Now
here is a way of determining what names are in common and then maybe
doing something:

B.names <- names(B.list)
A.names <- names(A.list)
common <- intersect(B.names, A.names)
for (i in common){
    B.list[[i]] <- function(A.list[[i]])
}
