[R] question on boot

[Lisa Wang]

Hello there:

Dear Dr. Murdoch,

I'm a statistician at Princess Margaret Hospital. Could you please help 
me with the bootstrapping?

Can boot function (along with boot.ci) handle multivariate statistics?  
My intention is that I want to group the outcome data and evaluate the 
proportion of patients who are positive for a marker within each group.  
(i.e. I have two variables, a predictor and an outcome.  The predictor 
is continuous and the outcome is binary.  I want a statistic which 
groups patients based on the predictor variable (0-10, 10-20, 20-30, 
etc;) and check the proportion of patients who are positive for the 
outcome variable within each group).

Regards
