trapez

This is a numerical integration of y with respect to
x by the trapezoidal method on linear scale.

Essentials for PK/PD (pharmacokinetics/pharmacodynamics) such as area under the curve, (geometric) coefficient of variation, and other calculations that are not part of base R. This is not a noncompartmental analysis (NCA) package.

trapez function

<dl><dt>x</dt>
<dd>The vector to integrate y with respect to (typically TIME
to get area under the curve).</dd>
<dt>y</dt>
<dd>The variable to integrate.</dd>
<dt>cum</dt>
<dd>Return the cumulative trapezoidal area under the curve?
If false (default) a single number is returned. If true, a
vector is returned. Notice, the vector is one element shorter
than x and y.</dd>
<dt>na.rm</dt>
<dd>Remove indexes in x and y wherever x or y are NA.</dd></dl>
