In R, there are several packages available that provide machine learning for the programmer. We will be using the following packages in the chapter:

• ada: This is used for stochastic boosting

• caret: This is used for classification and regression testing

• class: This package has classification functions

• clue: This package has the cluster ensemble methods

• e1071: This package has miscellaneous functions for the statistics department

• kernlab: This has kernel-based machine learning methods

• MASS: This stands for Modern Applied Statistics with S

• neuralnet: This has artificial neural net support

• randomForest: This has random forests for classification

• relaimpo: This package has functions to determine the relative importance of regressors in linear models
