I freely admit that I do not understand what you mean. But it sounds like you are trying to make things more complicated than necessary.
Perhaps this little example may help clarify the issues: > a <- 1; b <- 2; d <- c(3,5) > stuff <- lapply(list(a,b,d),function(x)x^2) > stuff [[1]] [1] 1 [[2]] [1] 4 [[3]] [1] 9 25 > stuff[[3]] [1] 9 25 Note that one may apply (almost) any function that returns objects (and doesn't have nasty side effects, I suppose), including graphical objects, and store them in the list that is returned. These objects can then be accessed as usual and manipulated/displayed/assigned ... whatever. If this misunderstands your query and is irrelevant, do not bother to explain. Or reply. Won't be the first time I did not get it. If OTOH this is a complete mystery to you, then you need to spend some time learning about R lists and how. to use them.
