<h2 class="section">D.16 <code>rmath</code></h2>

<p>A selection of mathematical and statistical functions from the GNU R
math library has a virtual code interface of the form
</p>
<table><tr><td>&nbsp;</td><td><pre class="example">library('rmath',f)
</pre></td></tr></table>

<p>where <code>f</code> is a character string derived from the name of a
function in the C language API described in the manual
&lsquo;<tt>R-exts.pdf</tt>&rsquo;, available at <a href="http://www.r-project.org">http://www.r-project.org</a>.
</p>
<p>Every function in the library returns a real result in the form of
<a href="math.html#math"><code>math</code></a>, but functions differ in the argument types. The arguments
are tuples of real numbers and booleans that also closely follow the
native API as explained below.
