Hello.

RPy version 0.2 is released. You can download it from the Sourceforge site:

http://rpy.sourceforge.net

WHAT IS RPy?

RPy is a very simple, yet robust, Python interface to the R Programming Language (http://www.r-project.org). It can manage all kinds of R objects and can execute arbitrary R functions (including the graphic functions). All the errors from the R language are converted to Python exceptions. Any module that later were installed on the R system, can easily be used from within Python, without introducing any changes. Currently it works only on POSIX systems.

CHANGES IN RPy 0.2

Fixed bugs

o There were several bugs related to memory and R and Python garbage collectors, which caused Python segfaults. o There was a problem with signals traped by R, which made Python crash when <Ctl-C> was pressed. o R objects of class 'factor' or 'data.frame' were incorrect converted to Python. o Instances of any class converted to R were treated as sequences and made Python segfault.

Conversion

o RPy has now a new system for conversion of types from R to Python (see the docs), which includes user defined conversion functions. o The conversion to R types is also customizable. o Some utility functions are added. o When Numeric (NumPy) is available, it is used for the standard conversion between R arrays and Python objects.

Documentation

o The documentation is converted to texinfo format, updated and enlarged. In particular, better documentation for the compilation procedure and for the location of libraries is included.

Distribution

o There are now some examples included in the distribution. o Regression tests are also included.
