Hi Everyone,
I am new in using R and I was wondering if anybody knows how to do a
leave-one-out cross-validation in R.
Thanks
Charles

You can use the caret or ipred packages. caret has it setup for specific models and can be used with parallel processing. ipred can do loo for any model since you manually code the model.
