Announcing the initial release of RSessionDA. RSessionDA provides Zope objects for interacting with R <http://www.r-project.org>, an open-source language for statistical computing and graphics. These objects permit evaluation of functions in the R language using information in Zope. R data objects, graphics files, printed output, script transcripts, and data files can be returned to Zope for display. These tools make it easy to create web applications that include advanced statistical functionality. RSessionDA is built on RSOAP package, which provides access to R via the SOAP <http://www.w3.org/TR/SOAP/"> communications protocol. This allows Zope to access multiple independent R sessions running (if desired) on a separate compute server.
