R users

R users rejoice: H2O-3 supports your chosen programming language!

Getting started with R

The following sections will help you begin using R for H2O-3.

See this cheatsheet on H2O-3 in R for a quick start.

Note

If you are running R on Linux, then you must install libcurl which allows H2O-3 to communicate with R. We also recommend disabling SElinux and any firewalls (at least initially until you confirmed H2O-3 can initialize).

  • On Ubuntu, run: apt-get install libcurl4-openssl-dev

  • On CentOS, run: yum install libcurl-devel

Installing H2O with R

You can find instructions for using H2O-3 with Python in the Downloading and installing H2O section and on the Downloads page.

From the Downloads page:

  1. Click the Install in R tab.

  2. Follow the on-page instructions.

Checking your R version for H2O-3

To check which version of H2O-3 is installed in R, run the following:

versions::installed.versions("h2o")

Note

R version 3.1.0 (“Spring Dance”) is incompatible with H2O-3. If you are using that version, we recommend upgrading your R version before using H2O-3.
