ggRandomForests (version 1.2.1)

partial_coplot_data: Cached plot.variable objects for examples, diagnostics and vignettes. Data sets storing rfsrc objects corresponding to training data according to the following naming convention:

• partial_coplot_Boston- randomForestS[R]C for theBostonhousing data set (MASSpackage).

Description

Cached plot.variable objects for examples, diagnostics and vignettes. Data sets storing rfsrc objects corresponding to training data according to the following naming convention:

• partial_coplot_Boston- randomForestS[R]C for theBostonhousing data set (MASSpackage).

format

List of plot.variable objects

Details

Constructing random forests are computationally expensive. We cache rfsrc objects to improve the ggRandomForests examples, diagnostics and vignettes run times. (see rfsrc_cache_datasets to rebuild a complete set of these data sets.)

For each data set listed, we build a rfsrc. Tuning parameters used in each case are documented in the examples. Each data set is built with the rfsrc_cache_datasets with the randomForestSRC version listed in the ggRandomForests DESCRIPTION file.

• partial_coplot_Boston- TheBostonhousing values in suburbs of Boston from theMASSpackage. Build a regression random forest for predicting medv (median home values) on 13 covariates and 506 observations.
