<p>Each system is characterized by the operating system type, the CPU
type, the mkin version, and, as in June 2022 the current R version lead
to worse performance, the R version. A compiler was available, so if no
analytical solution was available, compiled ODE models are used.</p>
<p>Every fit is only performed once, so the accuracy of the benchmarks
is limited.</p>
<p>The following wrapper function for <code>mmkin</code> is used because
the way the error model is specified was changed in mkin version
0.9.49.1.</p>
