The RShell plugin for Taverna enables scientists to run R scripts within the Taverna environment. The processor uses the standard R interpreter (www.r-project.org) and therefore is able to run almost any R script. The R processor supports different data types, amongst others numeric, literal and image typed data.
Detailed installation instructions for RShell can be found in the following document: RShell_Help.pdf
The software can be downloaded from: http://janus.cs.utwente.nl:8000/twiki/pub/BioRange/BioRangeSoftware/
