- </p>
- <p>
- For <i>rpy2</i>, check the <a href="rpy2.html">rpy2 page</a>

-
- <p>
- For installation instructions, please see the <a

-
- <p>
- For some systems, you may need to do some minor libraries arrangement,
- check the <a href="faq.html">FAQ</a>.
- </p>
-
- <h3>Notes for Window users:</h3>
-
- On Windows, you must install the following Python extensions
- in order to use RPy:
- <ul>
- <li>
- <a
href="http://starship.python.net/crew/mhammond/win32/Downloads.html";>
- Mark Hammond's Python extensions
- </a>
- (Conveniently included as part of
- <a href="http://www.activestate.com/Products/ActivePython/";>
- ActiveState Python
- </a>)
- </li>
-
-
- <li> "NumPy" python module:
- <a href="http://numpy.sf.net/";>Main page</a>
- <a
href="http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103";>
- Downloads</a>
- <b>Note that you need the <code>NumPy</code> module and
- <it>not</it> <code>Numeric</code></b>
- </li>
-
- </ul>
-
-
- You must use an Rpy binary that corresponds to the version of R,
- and Python you have installed. For example,
- <code>rpy-<b>0.4.6</b>-R-<b>2.0.0-to-2.2.1</b>-py<b>24</b>.win32.exe</code>
is for
- <ul>
- <li> RPy version <b>0.4.6</b> </li>
- <li> R versions <b>2.0.0 through 2.2.1</b> </li>
- <li> Python version <b>2.4</b> </Li>
- </ul>
-
- <h3>Developers</h3>
-
- <p>
- The development version of RPy can be accessed via CVS in the
- Sourceforge <a
- href="http://sourceforge.net/svn/?group_id=48422";>repository</a>.
- Be careful because the CVS version may be
- unstable.

href="mailto:tc...@optushome.com.au";>Tim Churches</a>
--->
-<p><b><a href="http://rpy.sourceforge.net/";>RPy</a></b>, written by Walter
Moreira and maintained by Gregory Warnes, is a Python extension module for
using the
-<a href="http://www.r-project.org";>R programming environment for data analysis
and graphics</a> from within <a href="http://www.python.org";>Python</a>.
-<p><b><a href="http://rpy.sourceforge.net/";>RPy</a></b> is available from the
<a href="http://rpy.sourceforge.net/";>RPy project web page</a>.
-As Walter notes, RPy was inspired by <a
href="http://www.omegahat.org/RSPython/index.html";>RSPython</a> by Duncan
Temple Lang. RSPython
-allows R to be called from Python <b>and</b> vice-versa (i.e. Python can be
embedded in R), as well as providing more general facilities for
-exploiting the object-oriented aspects of both Python and R. However, at least
for me, RPy is a lot easier to use. It is my sincere hope that
-RPy and RSPython can be merged in a display of el Norte/el Sur co-operation,
so we can have the best of both.
-
-<p>The following example provides a small taste of both the power of the R
environment and the ease with which RPy allows this power to be used from
within Python.
-<p>The data are eruption times for the Old Faithful geyser which, along with
Yogi Bear, is located in the Yellowstone National Park in Wyoming, USA.
-The data file <a href="faithful.dat">faithful.dat</a> was exported from the
faithful example dataset which comes as part of R. The R code in this
-example was borrowed directly from Section 8.2 of "<a
href="http://cran.r-project.org/manuals.html";>An Introduction to R, Version
1.4.1</a>" by W.N. Venables, D.M. Smith and the R Development Core Team.
-Minimal changes to the orginal R code were required to make it work from
within Python, thanks to RPy.

+<h3>A Demonstration of RPy: <a href="mailto:tc...@optushome.com.au";>Tim
Churches</a></h3>
+
+<p><b><a href="http://rpy.sourceforge.net/";>RPy</a></b>, written by Walter
Moreira and maintained by Gregory Warnes, is a Python extension module for
using the
+<a href="http://www.r-project.org";>R programming environment for data analysis
and graphics</a> from within <a href="http://www.python.org";>Python</a>.
+<p><b><a href="http://rpy.sourceforge.net/";>RPy</a></b> is available from the
<a href="http://rpy.sourceforge.net/";>RPy project web page</a>.
+As Walter notes, RPy was inspired by <a
href="http://www.omegahat.org/RSPython/index.html";>RSPython</a> by Duncan
Temple Lang. RSPython
+allows R to be called from Python <b>and</b> vice-versa (i.e. Python can be
embedded in R), as well as providing more general facilities for
+exploiting the object-oriented aspects of both Python and R. However, at least
for me, RPy is a lot easier to use. It is my sincere hope that
+RPy and RSPython can be merged in a display of el Norte/el Sur co-operation,
so we can have the best of both.
+
+<p>The following example provides a small taste of both the power of the R
environment and the ease with which RPy allows this power to be used from
within Python.
+<p>The data are eruption times for the Old Faithful geyser which, along with
Yogi Bear, is located in the Yellowstone National Park in Wyoming, USA.
+The data file <a href="faithful.dat">faithful.dat</a> was exported from the
faithful example dataset which comes as part of R. The R code in this
+example was borrowed directly from Section 8.2 of "<a
href="http://cran.r-project.org/manuals.html";>An Introduction to R, Version
1.4.1</a>" by W.N. Venables, D.M. Smith and the R Development Core Team.
+Minimal changes to the orginal R code were required to make it work from
within Python, thanks to RPy.
+
+<p>The following Python code (<a href="faithful.py">faithful.py</a>):
+<table>

+ <p>
+ You can download RPy from the
+ <a href="http://sourceforge.net/project/showfiles.php?group_id=48422";>
+ RPy Sourceforge downloads page
+ </a>.
+ </p>
+ <p>
+ For <i>rpy2</i>, check the <a href="rpy2.html">rpy2 page</a>
+ </p>
+
+ <h3>Installation</h3>
+
+ <p>
+ For installation instructions, please see the <a
+ href="rpy/README">README</a> file (this file is also included in
+ the source distribution).
+ </p>
+
+ <p>
+ For some systems, you may need to do some minor libraries arrangement,
+ check the <a href="faq.html">FAQ</a>.
+ </p>
+
+ <h3>Notes for Window users:</h3>
+
+ On Windows, you must install the following Python extensions
+ in order to use RPy:
+ <ul>
+ <li>
+ <a
href="http://starship.python.net/crew/mhammond/win32/Downloads.html";>
+ Mark Hammond's Python extensions
+ </a>
+ (Conveniently included as part of
+ <a href="http://www.activestate.com/Products/ActivePython/";>
+ ActiveState Python
+ </a>)
+ </li>
+
+
+ <li> "NumPy" python module:
+ <a href="http://numpy.sf.net/";>Main page</a>
+ <a
href="http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103";>
+ Downloads</a>
+ <b>Note that you need the <code>NumPy</code> module and
+ <it>not</it> <code>Numeric</code></b>
+ </li>
+
+ </ul>
+
+
+ You must use an Rpy binary that corresponds to the version of R,
+ and Python you have installed. For example,
+ <code>rpy-<b>0.4.6</b>-R-<b>2.0.0-to-2.2.1</b>-py<b>24</b>.win32.exe</code>
is for
+ <ul>
+ <li> RPy version <b>0.4.6</b> </li>
+ <li> R versions <b>2.0.0 through 2.2.1</b> </li>
+ <li> Python version <b>2.4</b> </Li>
+ </ul>
+
+ <h3>Developers</h3>
+
+ <p>
+ The development version of RPy can be accessed via CVS in the
+ Sourceforge <a
+ href="http://sourceforge.net/svn/?group_id=48422";>repository</a>.
+ Be careful because the CVS version may be
+ unstable.
