The BiG Grid R portal
To make using the grid easier, we're working a portal for users of the statistical programming language R. It's a web interface for your jobs, and a module for R. Plus some tools and language bindings to interact with the jobs.
As a bonus, you can also use it to run R on a GPU cluster.
The R portal is not a production service yet. We're currently looking for R users who want to help us to make it work smoothly in a real-world setting. If you're interested, please drop me a mail.
Note at this moment the LGI service is temporarily down because of hardware issues. We're sorry for the inconvenience and are working to get it back.

- read more about the Rlgi module for R.
- Slides of the R portal presentation at the BioAssist meeting of Feb, 2012.
The system is based on the Leiden Grid Intrastructure (LGI). It interacts with the grid using pilotjobs (read more).

On the grid, R 2.11 and 2.12 are available; the gpu cluster has versions 2.12 and 2.13.
