copied!<p>Well, imagine yourself as the setuptools packager and think of what you would expect the programmer to do.</p> <ul> <li>Setuptools knows nothing about R, its files' structure or that your code uses them somehow.</li> <li>Your R interpreter knows nothing about importing files from Python .egg's</li> </ul> <p>For the first problem, you have two choices:</p> <ol> <li>Tell setuptools to just include some additional files without bothering what they are</li> <li>Teach setuptools about R, how to determine what R files your program uses and how to track and include their dependencies</li> </ol> <p>The first option is implementable by passing <code>include_package_data = True</code> to <code>setup()</code> and providing masks of files to include in <code>package_data</code> (<a href="http://peak.telecommunity.com/DevCenter/setuptools#including-data-files" rel="nofollow">setuptools docs, "Including Data Files" section</a>). Paths relative to packages' directories can be used. The files will be accessible at run time at the same relative paths through the "Resource Management API" (<a href="http://svn.python.org/projects/sandbox/trunk/setuptools/setuptools.txt" rel="nofollow">"Accessing Data Files at Runtime" section</a>).</p> <p>The second option would require you to add your code to setuptools before invoking <code>setup()</code>. For example, you may <a href="http://peak.telecommunity.com/DevCenter/setuptools#adding-support-for-other-revision-control-systems" rel="nofollow">add a file finder</a> to add relevant .R files to the results of <code>find_packages()</code>. Or just generate the list of files for the previous paragraph by arbitrary means.</p> <p>For the second problem, the easiest way is to force setuptools to install the package as a directory rather than an .egg by specifying <a href="http://peak.telecommunity.com/DevCenter/setuptools#setting-the-zip-safe-flag" rel="nofollow"><code>zip_safe = False</code></a>. You might use <code>eager_resources</code> option instead that extracts a group of resources on demand (<a href="http://peak.telecommunity.com/DevCenter/setuptools#automatic-resource-extraction" rel="nofollow">"Automatic Resource Extraction" section</a>).</p> <p>As for installing third-party R packages, an automatable technique is described at <a href="http://cran.r-project.org/doc/manuals/R-admin.html#Installing-packages" rel="nofollow">R Installation and Administration - Installing packages</a></p>
