Extreme Gradient Boosting

Extreme Gradient Boosting, which is an efficient implementation of the gradient boosting framework from Chen & Guestrin (2016) <doi:10.1145/2939672.2939785>. This package is its R interface. The package includes efficient linear model solver and tree learning algorithms. The package can automatically do parallel computation on a single machine which could be more than 10 times faster than existing gradient boosting packages. It supports various objective functions, including regression, classification and ranking. The package is made to be extensible, so that users are also allowed to define their own objectives easily.

Functions in xgboost

Name	Description
prepare.ggplot.shap.data	Combine and melt feature values and SHAP contributions for sample observations.
dim.xgb.DMatrix	Dimensions of xgb.DMatrix
dimnames.xgb.DMatrix	Handling of column names of xgb.DMatrix
getinfo	Get information of an xgb.DMatrix object
cb.save.model	Callback closure for saving a model file.
print.xgb.cv.synchronous	Print xgb.cv result
print.xgb.DMatrix	Print xgb.DMatrix
cb.early.stop	Callback closure to activate the early stopping.
xgb.create.features	Create new features from a previously learned model
xgb.config	Accessors for model parameters as JSON string.
xgb.cv	Cross Validation
xgb.dump	Dump an xgboost model in text format.
xgb.model.dt.tree	Parse a boosted tree model text dump
xgb.parameters<-	Accessors for model parameters.
xgb.ggplot.deepness	Plot model trees deepness
xgb.ggplot.importance	Plot feature importance as a bar graph
predict.xgb.Booster	Predict method for eXtreme Gradient Boosting model
xgb.plot.multi.trees	Project all trees on one tree and plot it
normalize	Scale feature value to have mean 0, standard deviation 1
xgb.DMatrix.save	Save xgb.DMatrix object to binary file
xgb.attr	Accessors for serializable attributes of a model.
xgb.serialize	Serialize the booster instance into R's raw vector. The serialization method differs from xgb.save.raw as the latter one saves only the model but not parameters. This serialization format is not stable across different xgboost versions.
xgb.shap.data	Prepare data for SHAP plots. To be used in xgb.plot.shap, xgb.plot.shap.summary, etc. Internal utility function.
slice	Get a new DMatrix containing the specified rows of original xgb.DMatrix object
setinfo	Set information of an xgb.DMatrix object
xgb.ggplot.shap.summary	SHAP contribution dependency summary plot
xgb.gblinear.history	Extract gblinear coefficients history.
xgb.plot.shap	SHAP contribution dependency plots
xgb.save	Save xgboost model to binary file
xgb.save.raw	Save xgboost model to R's raw vector, user can call xgb.load.raw to load the model back from raw vector
xgb.importance	Importance of features in a model.
xgb.load.raw	Load serialised xgboost model from R's raw vector
xgb.load	Load xgboost model from binary file
xgb.plot.tree	Plot a boosted tree model
xgb.DMatrix	Construct xgb.DMatrix object
print.xgb.Booster	Print xgb.Booster
xgb.train	eXtreme Gradient Boosting Training
xgb.unserialize	Load the instance back from xgb.serialize
xgb.Booster.complete	Restore missing parts of an incomplete xgb.Booster object.
xgboost-deprecated	Deprecation notices.
cb.cv.predict	Callback closure for returning cross-validation based predictions.
callbacks	Callback closures for booster training.
agaricus.train	Training part from Mushroom Data Set
agaricus.test	Test part from Mushroom Data Set
a-compatibility-note-for-saveRDS-save	Do not use saveRDS or save for long-term archival of models. Instead, use xgb.save or xgb.save.raw.
cb.print.evaluation	Callback closure for printing the result of evaluation
cb.gblinear.history	Callback closure for collecting the model coefficients history of a gblinear booster during its training.
cb.reset.parameters	Callback closure for resetting the booster's parameters at each iteration.
cb.evaluation.log	Callback closure for logging the evaluation history
