<h1>Test the Embeddable R Library</h1>
|
|
|
9 |
|
|
|
10 |
This a collection of tests for verifying that using R as a library
|
|
|
11 |
within another application (i.e. embedded R) works for this
|
|
|
12 |
installation. This is only relevant if one has configured R with the
|
|
|
13 |
<code>--enable-R-shlib </code> argument for the top-level
|
|
|
14 |
<code>configure</code>. Currently, this only works for Unix,
|
| 25926 |
ripley |
15 |
and not Windows.

<h3>Test Applications</h3>
|
|
|
23 |
<dl>
|
|
|
24 |
<dt>
|
|
|
25 |
<li> <a href="Rtest.c">Rtest</a>
|
|
|
26 |
<dd>
|
|
|
27 |
Just prints the vector <code>c(1, 2, ..., 10)</code>
|
|
|
28 |
<dt>
|
|
|
29 |
<li> <a href="Rplot.c">Rplot</a>
|
|
|
30 |
<dd> Creates a basic plot of <code>c(1,2,..., 10)</code>
|
|
|
31 |
in the default device and then quits immediately.
|
|
|
32 |
<dt>
|
|
|
33 |
<li> <a href="Rpostscript.c">Rpostscript</a>
|
|
|
34 |
<dd>
|
|
|
35 |
Produces a plot of <code>1:100</code> using the Postscript
|
|
|
36 |
graphics device. This creates a file named <code>Rplots.ps</code>
|
|
|
37 |
|
|
|
38 |
<dt>
|
|
|
39 |
<li><a href="Rerror.c"> Rerror</a>
|
|
|
40 |
<dd> Reads a function definition from an external file (<a
|
|
|
41 |
href="code.R"><code>code.R</code></a>) and calls it
|
|
|
42 |
which in turn generates an "error" via <code>stop()</code>.
|
|
|
43 |
The local error handler defined for this application
|
|
|
44 |
catches this error and recovers.
|
|
|
45 |
|
|
|
46 |
<dt>
|
|
|
47 |
<li> <a href="RNamedCall.c">RNamedCall</a>
|
|
|
48 |
<dd> Calls a function with some named arguments.
|
|
|
49 |
|
|
|
50 |
<dt>
|
|
|
51 |
<li> <a href="RParseEval.c">RParseEval</a>
|
|
|
52 |
<dd> Parses a string and evaluates the resulting expression(s).
|
|
|
53 |
|
|
|
54 |
|
|
|
55 |
<dt>
|
|
|
56 |
<li> <a href="Rpackage.c">Rpackage</a>
|
|
|
57 |
<dd> Invokes <code>example()</code>
|
|
|
58 |
for functions in ctest and mva
|
|
|
59 |
to ensure that packages can be loaded
|
|
|
60 |
into R in an embedded context. These
|
|
|
61 |
packages must be linked against libR.so.
|
|
|
62 |
|
|
|
63 |
<dt>
|
|
|
64 |
<li> <a href="embeddedRCall.c">embeddedRCall.c</a>
|
|
|
65 |
<dd> Collection of routines used in the different
|
|
|
66 |
tests.

68 |
<li> Other Tests
|

69 |
<dd>
|
|

This has been tested in many other situations
|
|
|
71 |
including the some of the Omegahat packages:
|
|
|
72 |
<ul>
|
|
|
73 |
<li> As a procedural language within <a href="http://www.postgresql.org">Postsgres</a>.
|
|
|
74 |
See <a href="http://www.omegahat.org/DBMS/Postgres/R/RPostgres.pdf">R in Postgres</a>
|
|
|
75 |
<li> <a href="http://www.omegahat.org/RSJava">SJava</a>
|
|
|
76 |
<li> <a href="http://www.omegahat.org/SNetscape">SNetscape</a>
|
|

|
|
|
81 |
</ul>
|
|
|
82 |
These can be used as example code for embedding R within other applications.
