%description
Automatically builds 20 classification models from data. The package
returns 26 plots, 5 tables and a summary report. The package automatically
builds 12 individual classification models, including error (RMSE) and
predictions. That data is used to create an ensemble, which is then
modeled using 8 methods. The process is repeated as many times as the user
requests. The mean of the results are presented in a summary table. The
package returns the confusion matrices for all 20 models, tables of the
correlation of the numeric data, the results of the variance inflation
process, the head of the ensemble and the head of the data frame.
