I see that there are various approaches to bootstrapping, and I am wondering (1) which approach would be best for internal validation of predictive discrimination, (2) are there any good resources that could be recommended to explain the optimal approach, and (3) what packages in R should I use to achieve this approach.  Many thanks for the input.
