head2

Returns the first and last rows using output from both <code><a href="/link/head?package=popbio&version=2.8" data-mini-rdoc="popbio::head">head</a></code> and
<code><a href="/link/tail?package=popbio&version=2.8" data-mini-rdoc="popbio::tail">tail</a></code> and separates the two parts with dots. Useful for viewing
ordered datasets such as longitudinal census data.

Construct and analyze projection matrix models from a demography study of marked individuals classified by age or stage. The package covers methods described in Matrix Population Models by Caswell (2001) and Quantitative Conservation Biology by Morris and Doak (2002).
