⚠️There's a newer version (1.7.10.1) of this package.Take me there.

xgboost (version 1.5.2.1)

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.

callbacks

Callback closures for booster training.
cb.evaluation.log

Callback closure for logging the evaluation history
cb.early.stop

Callback closure to activate the early stopping.
cb.cv.predict

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

Handling of column names of xgb.DMatrix
xgb.attr

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

Save xgb.DMatrix object to binary file
setinfo

Set information of an xgb.DMatrix object
normalize

Scale feature value to have mean 0, standard deviation 1
predict.xgb.Booster

Predict method for eXtreme Gradient Boosting model
slice

Get a new DMatrix containing the specified rows of original xgb.DMatrix object
xgb.Booster.complete

Restore missing parts of an incomplete xgb.Booster object.
print.xgb.DMatrix

Print xgb.DMatrix
print.xgb.cv.synchronous

Print xgb.cv result
agaricus.test

Test part from Mushroom Data Set
xgb.DMatrix

Construct xgb.DMatrix object
prepare.ggplot.shap.data

Combine and melt feature values and SHAP contributions for sample observations.
xgb.set.config, xgb.get.config

Set and get global configuration
getinfo

Get information of an xgb.DMatrix object
xgb.load

Load xgboost model from binary file
xgb.load.raw

Load serialised xgboost model from R's raw vector
cb.save.model

Callback closure for saving a model file.
xgb.plot.multi.trees

Project all trees on one tree and plot it
print.xgb.Booster

Print xgb.Booster
xgb.plot.shap

SHAP contribution dependency plots
xgb.model.dt.tree

Parse a boosted tree model text dump
xgboost-deprecated

Deprecation notices.
xgb.ggplot.deepness

Plot model trees deepness
dim.xgb.DMatrix

Dimensions of xgb.DMatrix
xgb.create.features

Create new features from a previously learned model
xgb.config

Accessors for model parameters as JSON string.
xgb.parameters<-

Accessors for model parameters.
xgb.unserialize

Load the instance back from xgb.serialize
xgb.train

eXtreme Gradient Boosting Training
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.ggplot.shap.summary

SHAP contribution dependency summary plot
xgb.ggplot.importance

Plot feature importance as a bar graph
xgb.plot.tree

Plot a boosted tree model
xgb.cv

Cross Validation
xgb.dump

Dump an xgboost model in text format.
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.importance

Importance of features in a model.
xgb.gblinear.history

Extract gblinear coefficients history.
xgb.shap.data

Prepare data for SHAP plots. To be used in xgb.plot.shap, xgb.plot.shap.summary, etc. Internal utility function.
agaricus.train

Training part from Mushroom Data Set
cb.print.evaluation

Callback closure for printing the result of evaluation
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.reset.parameters

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