Subject: list concatenation
In-Reply-To: <m2ei8jsavl.fsf@georgotto.de>
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.
