Dear R--Help,

My current research focuses upon sensitivity analyses which require [1] 
clusterings of patients in a baseline-covariate X space and [2] examining 
the distribution of within-cluster treatment differences in outcome.  I 
have some primitive R code for this, but I want to be able to interact 
with graphical displays of within-cluster information (local average 
treatment effects) to identify individual clusters and/or compare pairs of 
clusters in terms for the X characteristics of their patients.

Is anybody currently working on developing this sort of point-and-click 
capability in R?  I would be very interested in becoming an alpha or beta 
tester of this functionality.

If some computer scientist is looking for a thesis topic involving 
applications of graphics and statistical methods in health care 
(randomized or nonrandomized studies), I would be happy to send a recent 
white paper on the methodology I visualize.  On top of my work at Lilly, I 
am an adjunct professor of biostatistics at Indiana University Medical 
School and would be willing to participate on a thesis committee.

For example, I can perform almost all of the point-and-click operations I 
am interested in from existing menu items in JMP version 5.1, but I have 
not been able to develop usable JMP scripts to automate the basic 
processes.  ...BobO.
