Dear R-devel,

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 

I have generated some primitive R code for this, but I really need 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.   ...BobO.
