H₂O in R Studio

Installation of H₂O Package in R

These instructions assume you are using R Studio 2.14.0 or later.

STEP 1

The download package can be obtained by clicking on the button Download H₂O at http://0xdata.com/downloadtable.

Unzip the downloaded H₂O zip file.

STEP 2

Start an instance of H₂O. For help with this see Getting Started from a Downloaded Zip File

Users should be aware that in order for H₂O to successfully run through R, an instance of H₂O must also simultaneously be running. If the instance of H₂O is stopped, the R program will no longer run, and work done will be lost.

STEP 3: R Studio Users

Install the H₂O package, and the H₂O client package simultaneously by clicking on install package

Walk through the installer helper to the H₂O downloaded folder.

Once the correct path has been specified click “Install.” This will install the package in R.

Start the H₂O package by clicking the check box next to the package name “h2o”.

STEP 4

Get R Studio talking to your instance of H₂O by typing in the call:

>localH2O = h2o.init(ip = "localhost", port = 54321, startH2O = TRUE, silentUpgrade = FALSE, promptUpgrade = TRUE)

Your IP and port may be different, depending on whether you are running H₂O from your computer or a server. If you are running on a server, where it says IP enter the IP address of the server, and the appropriate port number. In the picture below the IP number is everything before the colon, and the port number is the 5 digit string after the colon.

Upgrading the H₂O R Packages

Users may wish to manually upgrade their R packages. For instance, if you are running the bleeding edge developer build, it’s possible that the code has changed, but that the revision number has not, in which case manually upgrading ensures the most current version of not only the H2O code, but the corresponding R code as well.
