wolves

A data set containing skull morphometric measurements on Rocky Mountain
 and Arctic wolves (Canis Lupus L.). The tdata are published in Morrison (1990),
 originally from Jolicoeur (1959).

wolves function

A data frame with 25 rows and 12 variables.
The variables are as follows (all measurements are in milimeters):
<ul>
<li><code>class</code>: a factor presenting the combinations of <code>location</code>
 and <code>sex</code>. The levels are <code>arf</code> <code>arm</code> <code>rmf</code> and <code>rmm</code></li>
<li><code>location</code>: a factor with levels <code>ar</code>=Arctic, <code>rm</code>=Rocky Mountain</li>
<li><code>sex</code>: a factor with levels <code>f</code>=female, <code>m</code>=male</li>
<li><code>x1</code>: palatal length</li>
<li><code>x2</code>: postpalatal length</li>
<li><code>x3</code>: zygomatic width</li>
<li><code>x4</code>: palatal width outside first upper molars</li>
<li><code>x5</code>: palatal width inside second upper molars</li>
<li><code>x6</code>: postglenoid foramina width</li>
<li><code>x7</code>: interorbital width</li>
<li><code>x8</code>: braincase width</li>
<li><code>x9</code>: crown length</li>
</ul>
