tmp <- createDataPartition(logBBB,p = .8, times = 100)
trControl = trainControl(method = "LGOCV", index = tmp)
ctreeFit <- train(bbbDescr, logBBB, "ctree",trControl=trControl)
*************************************
My questions are:
1) If I use createDataPartition (which I assume that does stratified
bootstrapping), as in the above example, and I pass the result as index to
trainControl do I need to use LGOCV as the method...
