<h2 class="hasAnchor" id="arguments"><a class="anchor" href="#arguments"></a> Arguments</h2>
<dl class="dl-horizontal">
<dt>x</dt>
<dd>When numeric, this is the half-life to be used for an exponential
decline. When a character string specifying a parent decline model is given
e.g. <code>FOMC</code>, <code>parms</code> must contain the corresponding paramters.
If x is an <code>mkinfit</code> object, the decline is calculated from this
object.</dd>
<dt>ini</dt>
<dd>The initial amount. If x is an <code>mkinfit</code> object, and
ini is 'model', the fitted initial concentrations are used. Otherwise, ini
must be numeric. If it has length one, it is used for the parent and
initial values of metabolites are zero, otherwise, it must give values for
all observed variables.</dd>
