Plot Variable Importances

Usage

1
h2o.varimp_plot(model, num_of_features = NULL)

Arguments

model

A trained model (accepts a trained random forest, GBM, or deep learning model, will use h2o.std_coef_plot for a trained GLM

num_of_features

The number of features shown in the plot (default is 10 or all if less than 10).
