These are often external but might have been compiled into <span style="font-family: Courier New, Courier; color: #666666;"><b>R</b></span> when it was installed. </p> <p>With dynamic linking, these are the versions of the libraries linked to in this session: with static linking, of those compiled in. </p> <h3>Value</h3> <p>A named character vector, currently with components </p> <table summary="R valueblock"> <tr valign="top"><td><code>zlib</code></td> <td> <p>The version of <code>zlib</code> in use.</p> </td></tr> <tr valign="top"><td><code>bzlib</code></td> <td> <p>The version of <code>bzlib</code> (from <code>bzip2</code>) in use.</p> </td></tr> <tr valign="top"><td><code>xz</code></td> <td> <p>The version of <code>liblzma</code> (from <code>xz</code>) in use.</p> </td></tr> <tr valign="top"><td><code>PCRE</code></td> <td> <p>The version of <code>PCRE</code> in use.</p> </td></tr> <tr valign="top"><td><code>ICU</code></td> <td> <p>The version of <code>ICU</code> in use (if any, otherwise <code>""</code>).</p> </td></tr> <tr valign="top"><td><code>TRE</code></td> <td> <p>The version of <code>libtre</code> in use.</p> </td></tr> <tr valign="top"><td><code>iconv</code></td> <td> <p>The implementation and version of the <code>iconv</code> library in use (if known).</p> </td></tr> <tr valign="top"><td><code>readline</code></td> <td> <p>The version of <code>readline</code> in use (if any, otherwise <code>""</code>).</p> </td></tr> <tr valign="top"><td><code>BLAS</code></td> <td> <p>Name of the binary/executable file with the implementation of <code>BLAS</code> in use (if known, otherwise <code>""</code>).</p> </td></tr> </table> <p>Note that the values for <code>bzlib</code> and <code>pcre</code> normally contain a date as well as the version number, and that for <code>tre</code> includes several items separated by spaces, the version number being the second. </p> <p>For <code>iconv</code> this will give the implementation as well as the version, for example <code>"GNU libiconv 1.14"</code>, <code>"glibc 2.18"</code> or <code>"win_iconv"</code> (which has no version number). </p> <p>The name of the binary/executable file for <code>BLAS</code> can be used as an indication of which implementation is in use. Typically, the R version of BLAS will appear as <code>libR.so</code> (<code>libR.dylib</code>), <code>R</code> or <code>libRblas.so</code> (<code>libRblas.dylib</code>), depending on how R was built. Note that <code>libRblas.so</code> (<code>libRblas.dylib</code>) may also be shown for an external BLAS implementation that had been copied, hard-linked or renamed by the system administrator. For an external BLAS, a shared object file will be given and its path/name may indicate the vendor/version. The detection does not work on Windows. </p> <h3>See Also</h3> <p><code><a href="libcurlVersion.html">libcurlVersion</a></code> for the version of <code>libCurl</code>. </p> <p><code><a href="La_version.html">La_version</a></code> for the version of LAPACK in use. </p> <p><code><a href="La_library.html">La_library</a></code> for binary/executable file with LAPACK in use. </p> <p><code><a href="../../grDevices/html/grSoftVersion.html">grSoftVersion</a></code> for third-party graphics software. </p> <p><code><a href="../../tcltk/html/TclInterface.html">tclVersion</a></code> for the version of Tcl/Tk. </p> <p><code><a href="pcre_config.html">pcre_config</a></code> for PCRE configuration options. </p> <h3>Examples</h3> <pre> extSoftVersion() ## the PCRE version sub(" .*", "", extSoftVersion()["PCRE"]) </pre> <hr /><div style="text-align: center;">[Package <em>base</em> version 3.6.0 <a href="00Index.html">Index</a>]</div> </body></html>
