create_pm

Creates a simple skeleton <code>paramnames</code> object that can be entered as
input in functions <code>flefko2()</code>, <code>flefko3()</code>, and
<code>aflefko2()</code>.

Complete analytical environment for the construction and analysis
of matrix population models and integral projection models.
Includes the ability to construct historical matrices, which are
2d matrices comprising 3 consecutive times of demographic
information. Estimates both raw and function-based forms of
historical and standard ahistorical matrices. It also estimates
function-based age-by-stage matrices and raw and function-based
Leslie matrices.

create_pm function

<dl><dt>name_terms</dt>
<dd>A logical value indicating whether to start each variable
name as <code>none</code> if <code>FALSE</code>, or as the default <code>modelparams</code>
name if <code>TRUE</code>. Defaults to <code>FALSE</code>.</dd></dl>

Arguments

The third column in the resulting object should be edited with the names only
of those variables actually used in vital rate modeling. This
<code>paramnames</code> object should apply to all models used in a single MPM
building exercise. So, for example, if the models used include random terms,
then they should all have the same random terms. Fixed terms can vary,
however.
