The h2o package

The R software .exe file size is 75 MB (version 3.4.1). The size of the h2o R package is 125 MB. This will probably indicate to you the importance of the h2o package. All the datasets used in this book are very limited in size, with the number of observations not exceeding 10,000. In most cases, the file size has been of a maximum of a few MB. However, the data science world works hard, and throws around files in GB, and in even higher formats. Thus, we need more capabilities, and the h2o package provides just that. We simply load the h2o package and have a peek:

> library(h2o)

Your next step is to start H2O:
    > h2o.init()

For H2O package documentation, ask for help:
    > ??h2o

After starting H2O, you can use the Web UI at http://localhost:54321
