RPy Version 0.3.3 is now available from the RPy home page at http://rpy.sf.net.
What is RPy? --------------------
RPy is a very simple, yet robust, Python (http://www.python.org) interface to the R environment for statistical data analysis and graphics (http://www.r-project.org). RPy can manages translation between python and R formats for all kinds of R objects and can execute arbitrary R functions (including the graphic functions). All errors from the R language are converted to proper Python exceptions. All module installed on the R system are available from Python.
Consequently, RPy allows Python programmers to easily add advanced statistical functionality to Python programs. It allows R programmers the ability to use Python to control R computations and to interface them with other systems. Examples include RSOAP (http://www.analytics.washington.edu/Zope/projects/RSOAP), RSessionDA (http://www.analytics.washington.edu/Zope/projects/RSOAP), and RStatServer (http://www.analytics.washington.edu/Zope/projects/RStatServer). These products, which make heavy use of RPy have been used in a production environments for two years.
New features in 0.3.3 -------------------------------
o Now works with R 1.8.X
o Windows version merged into the Unix source tree
o Added lcall() method for calling R functions using a list of (name, value) pairs for the parameters. This is works around the python (mis-)feature of using unordered python dictionaries for named parameters, resulting in the loss of order for named parameters.
o All reported bugs have been fixed.
o New maintainer: Gregory R. Warnes firstname.lastname@example.org
