Getting ready

To set up H2O, the following systems are required:

• 64-bit Java Runtime Environment (version 1.6 or later)
• Minimum 2 GB RAM

H2O from R can be called using the h2o package. The h2o package has the following dependencies:

• RCurl
• rjson
• statmod
• survival
• stats
• tools
• utils
• methods

For machines that do not have curl-config installed, the RCurl dependency installation will fail in R and curl-config needs to be installed outside R.
