I'm really glad to see this topic come up. Area-proportional Venn diagrams
are a phantastic way to visualize agreement. For the 2-rater scenario this
is straightforward; here are two examples from my own work that were done in
R. (I'm far too embarrassed to enclose the code).

Dear all,
hist ( ) plots a horizontal line at y=0 when the respective bin is empty. I
can deal with this by modifying the hist object before plotting it
(x$density[x$density == 0] <- NA), but I'm sure I've seen a more elegant
way. Perhaps this was in truehist (MASS). I have looked but can't find
Assign the output of coxph to some object, and use the $ extractor function
to obtain what you need.
ie:
rtfm <- coxph(formula = Surv(time, status) ~ age + sex + disease +
frailty(id, dist = "gauss"), data = kidney)
Age <- coef(rtfm)["age"]
OR
Sex <- rtfm$coef["sex"]
Hope this helps.

Its a very nice document. Here is the link:

Most useful: the Ungroup command in ppt lets you take apart the graph when
you insert it as wmf.
I often resort to that when I want to change labels / fonts / colours etc.
Very flexible.

Dear Anderson,
I'd highly recommend "Modern Applied Statistics with S" (4th Ed., by WN
Venables & BD Ripley). This has lots and lots of material on the topics of
your interest.
Best wishes
Paul
