We will also show you how to use H2O for some of the exercises. The easiest way to install H2O is to get it from CRAN. 

It has a few dependencies, notably the packages:

• RCurl
• bitops
• rjson
• statmod
• tools

If you run into trouble, chances are that there is some dependency missing. Re-read the error message and install any missing packages. 

If it all goes smoothly, import the library and initialize the service to check that everything works:

install.packages("h2o")
library(h2o)
h2o.init()
