By default the same as the <em>current</em> library path. I.e. <em>not</em> necessarily the library path of a fresh R session.) </p> </li> <li> <p><code>repos</code>: <code>repos</code> option for the subprocess. By default the current value of the main process. </p> </li> <li> <p><code>stdout</code>: Standard output of the sub-process. This can be <code>NULL</code> or a pipe: <code>"|"</code>. If it is a pipe then the output of the subprocess is not included in the responses, but you need to poll and read it manually. This is for experts. Note that this option is not used for the startup phase that currently always runs with <code>stdout = "|"</code>. </p> </li> <li> <p><code>stderr</code>: Similar to <code>stdout</code>, but for the standard error. Like <code>stdout</code>, it is not used for the startup phase, which runs with <code>stderr = "|"</code>. </p> </li> <li> <p><code>error</code>: See 'Error handling' in <code><a href="r.html">r()</a></code>. </p> </li> <li> <p><code>cmdargs</code>: See the same argument of <code><a href="r.html">r()</a></code>. (Its default might be different, though.) </p> </li> <li> <p><code>system_profile</code>: See the same argument of <code><a href="r.html">r()</a></code>. </p> </li> <li> <p><code>user_profile</code>: See the same argument of <code><a href="r.html">r()</a></code>. </p> </li> <li> <p><code>env</code>: See the same argument of <code><a href="r.html">r()</a></code>. </p> </li> <li> <p><code>load_hook</code>: <code>NULL</code>, or code (quoted) to run in the sub-process at start up. (I.e. not for every single <code>run()</code> call.) </p> </li> <li> <p><code>extra</code>: List of extra arguments to pass to <a href="../../processx/html/process.html">processx::process</a>. </p> </li></ul> <p>Call <code>r_session_options()</code> to see the default values. <code>r_session_options()</code> might contain undocumented entries, you cannot change these. </p> <h3>Examples</h3> <pre> r_session_options() </pre> <hr /><div style="text-align: center;">[Package <em>callr</em> version 3.7.2 <a href="00Index.html">Index</a>]</div> </body></html>
