e <code>params</code> argument supplies all of the ecological parameters necessary
to calculate equilibrium values. This function requires the <code>nE</code>,
<code>nL</code>, and <code>nP</code> parameters to be specified. For more details, see
<code><a href='equilibrium_lifeycle.html'>equilibrium_lifeycle</a></code></p>
<p>While this function produces all structural information related to transitions,
hazards are produced by a separate function, <code><a href='spn_hazards.html'>spn_hazards</a></code>.</p
