[R] list concatenation

[David Katz]

Without any error checking, I'd try this:

recurse <-
    function(l1,l2){
        if(is(l1[[1]],"list"))
            mapply(recurse,l1,l2,SIMPLIFY=F) else
{mapply(c,l1,l2,SIMPLIFY=F)}
    }

recurse(list.1,list.2)

which recursively traverses each tree (list) in tandem until one is not
composed of lists and then concatenates. If the structure of the lists does
not agree, this will fail.
