<h1>Test the Embeddable R Library</h1>
This a collection of tests for verifying that using R as a library
within another application (i.e. embedded R) works for this
installation. This is only relevant if one has configured R with the
<code>--enable-R-shlib </code> argument for the top-level
<code>configure</code>.
<p>
More information can be found at the
<a href="http://developer.r-project.org/embedded.html">R Developer's site</a>
<h3>Test Applications</h3>
<dl>
<dt>
<li> <a href="Rtest.c">Rtest</a>
<dd>
Just prints the vector <code>c(1, 2, ..., 10)</code>
<dt>
<li> <a href="Rplot.c">Rplot</a>
<dd> Creates a basic plot of <code>c(1,2,..., 10)</code>
in the default device and then quits immediately.
<dt>
<li> <a href="Rpostscript.c">Rpostscript</a>
<dd>
Produces a plot of <code>1:100</code> using the Postscript
graphics device. This creates a file named <code>Rplots.ps</code>
<dt>
<li><a href="Rerror.c"> Rerror</a>
<dd> Reads a function definition from an external file (<a
href="code.R"><code>code.R</code></a>) and calls it
which in turn generates an "error" via <code>stop()</code>.
The local error handler defined for this application
catches this error and recovers.
<dt>
<li> <a href="RNamedCall.c">RNamedCall</a>
<dd> Calls a function with some named arguments.
<dt>
<li> <a href="RParseEval.c">RParseEval</a>
<dd> Parses a string and evaluates the resulting expression(s).
<dt>
<li> <a href="Rpackage.c">Rpackage</a>
<dd> Invokes <code>example()</code>
for functions in ctest and mva
to ensure that packages can be loaded
into R in an embedded context. These
packages must be linked against libR.so.
<dt>
<li> <a href="embeddedRCall.c">embeddedRCall.c</a>
<dd> Collection of routines used in the different
tests.
<dt>
<li> Other Tests
<dd>
This has been tested in many other situations
including the some of the Omegahat packages:
<ul>
<li> As a procedural language within <a href="http://www.postgresql.org">Postsgres</a>.
See <a href="http://www.omegahat.org/DBMS/Postgres/R/RPostgres.pdf">R in Postgres</a>
<li> <a href="http://www.omegahat.org/RSJava">SJava</a>
<li> <a href="http://www.omegahat.org/SNetscape">SNetscape</a>
<li> <a href="http://www.omegahat.org/SXalan">SXalan</a>
<li> <a href="http://www.omegahat.org/SXalan">SXalan</a>
<li> <a href="http://www.omegahat.org/RSPython">RSPython</a>
<li> <a href="http://www.omegahat.org/RSPerl">RSPerl</a>
</ul>
These can be used as example code for embedding R within other applications.
