I'll send you my (unpublished) version of my package 'bagplot' {{the one I've never released because of segmentation fault bugs somewhere in Fortran}} in a private E-mail.

In my version I had started make a function

bag()

which *computes* all the information needed and then returns an
(S3) object "bag". Then, the plotting happens via
the

plot.bag <- function(.....) {..........} method.

So you can say

plot(bag(.........), ........)

if you want both (computing and plotting) at once, but can also separate the two --- following very much the modern "S" way "whole object ..".
