OpenML aims to create a frictionless, collaborative environment for exploring machine learning. This R package allows to interface the OpenML server to download datasets, tasks, runs and upload results (see Tutorial).

To cite the OpenML R package in publications, please use our paper.

• Install the stable version from CRAN

install.packages("OpenML")

or

• Install the development version from GitHub (using devtools)

devtools::install_github("openml/openml-r")

Furthermore, you need farff installed to process ARFF files:

install.packages("farff")

Alternatively you can make use of the RWeka R package to process ARFF files. However, in particular for larger ARFF files, farff is considerably faster than RWeka.

Found some nasty bugs? Please use the issue tracker to report on bugs or missing features. Pay attention to explain the problem as good as possible (in the best case with a traceback() result and a sessionInfo()). Moreover, a reproducible example is desirable.
