I'll send you my (unpublished) version of my package 'bagplot'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 ..".
