man/set_excluded_class_id.Rd (1)
7-12: Ensure consistency in parameter description.The parameter
is_classis now described as a logical vector. Ensure that this change is consistently reflected in all related documentation and usage examples.Verification successful
Documentation is consistent with code changes.
The parameter
is_classis correctly documented as a logical vector inman/set_excluded_class_id.Rd, matching its usage in the code. No further inconsistencies were found.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify that the parameter `is_class` is consistently used and documented across the codebase. # Test: Search for usage of `set_excluded_class_id`. Expect: Consistent use of `is_class`. rg --type r 'set_excluded_class_id'Length of output: 171

man/isClassifierAndValidate.Rd (1)
3-18: Update documentation to reflect function's new purpose.The function
isClassifierAndValidatenow returns a logical value, indicating whether a model is a classifier. Ensure the description emphasizes this validation aspect and that all references to the function have been updated.Verification successful
Documentation is consistent with function usage.
The
isClassifierAndValidatefunction is consistently used across the codebase, and its documentation correctly reflects its purpose of validating model types by returning a logical value. No further updates are necessary.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify that the function `isClassifierAndValidate` is consistently used and documented across the codebase. # Test: Search for usage of `isClassifierAndValidate`. Expect: Consistent use and updated references. rg --type r 'isClassifierAndValidate'Length of output: 3562
tests/testthat/test-caretEnsemble.R (1)
248-250: Verify the updated function usage in the test case.The test now uses
stackedTrainResidualsto handle missing predictions. Ensure that this function is correctly implemented and that its usage aligns with the test's purpose.Verification successful
The function
stackedTrainResidualsis correctly implemented and used in the test case. The test case appropriately checks for scenarios with missing predictions, aligning with the function's logic. The message about settingsavePredictions = 'final'is relevant and accurate.
- The function handles both regression and classification tasks by calculating residuals.
- The test case correctly uses this function to verify behavior when predictions are not saved.

R/caretPredict.R (6)
93-95: Efficient use ofextractBestPreds.The update to save only the best predictions using
extractBestPredsis efficient and improves the code.
126-137: Correct aggregation logic.The
aggregate_mean_or_firstfunction correctly handles numeric and character data aggregation.
139-172: Well-structured prediction extraction.The
extractBestPredsfunction is well-structured and efficiently handles the extraction and averaging of predictions.
344-357: Accurate classifier identification.The
isClassifierfunction accurately identifies classifier models.
359-391: Comprehensive validation checks.The
isClassifierAndValidatefunction includes comprehensive validation checks, enhancing robustness.

12-45:
LGTM! But verify the function usage in the codebase.The refactoring of
caretPredictenhances readability and maintainability by using helper functions. The changes are approved.However, ensure that all function calls to
caretPredicthandle the new logic correctly.Verification successful
Function usage verified and correct
The function
caretPredictis used in various parts of the codebase, including tests that validate its behavior. The integration appears correct and consistent with the refactoring.

Improved readability and data retention.The refactoring of
caretListenhances readability and ensures class probabilities are saved, which is crucial for classification tasks.tests/testthat/test-helper_functions.R (5)
Line range hint
26-50:
Thorough testing of validation logic.The test updates ensure that the new
isClassifierAndValidatefunction is thoroughly tested for logical outputs.
177-181: Correct handling of missing probability functions.The test correctly ensures that
isClassifierAndValidatestops when a model can't predict probabilities.
184-188: Correct handling of missing saved probabilities.The test ensures that
isClassifierAndValidatestops when class probabilities are not saved, which is crucial for classification.
170-174: Comprehensive validation of excluded class levels.The test ensures that
validateExcludedClasshandles various input scenarios correctly, covering edge cases.
457-463: Correct handling of missingsavePredictions.The test ensures that
isClassifierAndValidatefails whensavePredictionsis not set, which is essential for stacked predictions.R/caretStack.R (2)
146-149: LGTM! Improved clarity withisClassifier.The replacement of direct model type checks with
isClassifier(object)enhances readability and maintainability.
226-231: LGTM! Simplified parameter usage.The function now uses a boolean
is_classto determine if the model is a classifier, which simplifies the logic.
