⚠️There's a newer version (1.7.8.1) of this package.Take me there.

xgboost (version 1.1.1.1)

Extreme Gradient Boosting

Description

Extreme Gradient Boosting, which is an efficient implementation of the gradient boosting framework from Chen & Guestrin (2016) . 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 (1.1.1.1)

cb.cv.predict

Callback closure for returning cross-validation based predictions.
print.xgb.DMatrix

Print xgb.DMatrix
print.xgb.Booster

Print xgb.Booster
xgb.DMatrix

Construct xgb.DMatrix object
getinfo

Get information of an xgb.DMatrix object
xgb.DMatrix.save

Save xgb.DMatrix object to binary file
predict.xgb.Booster

Predict method for eXtreme Gradient Boosting model
xgb.attr

Accessors for serializable attributes of a model.
dim.xgb.DMatrix

Dimensions of xgb.DMatrix
dimnames.xgb.DMatrix

Handling of column names of xgb.DMatrix
slice

Get a new DMatrix containing the specified rows of original xgb.DMatrix object
xgb.plot.multi.trees

Project all trees on one tree and plot it
xgb.ggplot.importance

Plot feature importance as a bar graph
xgb.config

Accessors for model parameters as JSON string.
print.xgb.cv.synchronous

Print xgb.cv result
xgb.gblinear.history

Extract gblinear coefficients history.
xgb.dump

Dump an xgboost model in text format.
setinfo

Set information of an xgb.DMatrix object
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.save

Save xgboost model to binary file
xgb.create.features

Create new features from a previously learned model
xgb.plot.tree

Plot a boosted tree model
xgb.cv

Cross Validation
xgb.plot.shap

SHAP contribution dependency plots
xgb.Booster.complete

Restore missing parts of an incomplete xgb.Booster object.
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.load.raw

Load serialised xgboost model from R's raw vector
xgb.train

eXtreme Gradient Boosting Training
xgb.model.dt.tree

Parse a boosted tree model text dump
xgb.importance

Importance of features in a model.
xgb.parameters<-

Accessors for model parameters.
xgb.unserialize

Load the instance back from xgb.serialize
xgb.ggplot.deepness

Plot model trees deepness
xgboost-deprecated

Deprecation notices.
xgb.load

Load xgboost model from binary file
cb.early.stop

Callback closure to activate the early stopping.
cb.reset.parameters

Callback closure for resetting the booster's parameters at each iteration.
cb.gblinear.history

Callback closure for collecting the model coefficients history of a gblinear booster during its training.
agaricus.test

Test part from Mushroom Data Set
cb.print.evaluation

Callback closure for printing the result of evaluation
callbacks

Callback closures for booster training.
cb.save.model

Callback closure for saving a model file.
cb.evaluation.log

Callback closure for logging the evaluation history
agaricus.train

Training part from Mushroom Data Set
