| <h1>Test the Embeddable R Library</h1> |
| |
| <p> |
| 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> |

| <h3>Test Applications</h3> |
| <dl> |
| <dt> |
| <a href="Rtest.c">Rtest</a> |
| </dt> |
| <dd> |
| Just prints the vector <code>c(1, 2, ..., 10)</code> |
| </dd> |
| <dt> |
| <a href="Rplot.c">Rplot</a> |
| </dt> |
| <dd> |
| Creates a basic plot of <code>c(1,2,..., 10)</code> |
| in the default device and then quits immediately. |
| </dd> |
| <dt> |
| <a href="Rpostscript.c">Rpostscript</a> |
| </dt> |
| <dd> |
| Produces a plot of <code>1:100</code> using the Postscript |
| graphics device. This creates a file named <code>Rplots.ps</code> |
| </dd> |
| <dt> |
| <a href="Rerror.c"> Rerror</a> |
| </dt> |
| <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. |
| </dd> |
| <dt> |
| <a href="RNamedCall.c">RNamedCall</a> |
| </dt> |
| <dd> |
| Calls a function with some named arguments. |
| </dd> |
| <dt> |
| <a href="RParseEval.c">RParseEval</a> |
| </dt> |
| <dd> |
| Parses a string and evaluates the resulting expression(s). |
| </dd> |
| <dt> |
| <a href="Rpackage.c">Rpackage</a> |
| </dt> |
| <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. |
| </dd> |
| <dt> |
| <a href="embeddedRCall.c">embeddedRCall.c</a> |
| </dt> |
| <dd> |
| Collection of routines used in the different tests. |
| </dd> |
| <dt> |
| Other Tests |
| </dt> |
| <dd> |
| This has been tested in many other situations including the some of |
| the former Omegahat packages: |
| <ul> |
| <li> |
| As a procedural language within <a href="https://www.postgresql.org">Postsgres</a>. |
| See <a href="https://www.omegahat.net/DBMS/Postgres/R/RPostgres.pdf">R |
| in Postgres</a> |
| </li> |

| </li> |
| <li> |
| <a href="https://www.omegahat.net/RSPerl">RSPerl</a> |
| </li> |
| </ul> |
| These can be used as example code for embedding R within other |
| applications. |
