in XGBoost: iteration_range should be used instead of ntree_limit

[shainova]

I get error:
[11:52:40] WARNING: src/c_api/c_api.cc:935: ntree_limit is deprecated, use iteration_range instead.

Running:

train_control <- trainControl(
  method = "cv",           # Cross-validation
  number = 5,              # 5-fold CV
  summaryFunction = balancedAccuracy,  # Use balanced accuracy to evaluate models
  savePredictions = "final"
)

xgb_model <- train(
  y ~ .,
  data = train_data,
  method = "xgbTree",
  trControl = train_control,
  tuneLength = 3  # Number of hyperparameter combinations to try
)

You can follow this. Just add verbosity = 0 within train function. As suggested by missuse "The current warning means xgboost is changing the name of an argument, but caret is still supplying the old name. Currently, it works but with new xgboost versions the argument will be completely replaced, if carets function code is not updated by then the warning will be replaced by an error." So, it would be better to update the caret function code.
