<h2>File List</h2><blockquote>
<p><a href="frogindex.Rdump">frogindex.Rdump</a></p>
<p>
</p></blockquote><h2>Description</h2><blockquote>
<p>The file frogindex.Rdump is an <b>R</b> dump file that contains 3 <b>R</b> objects. This file should be loaded into <b>R</b> by issuing the command source("frogindex.Rdump") from an active <b>R</b> session. This will yield 3 objects defined subsequently. The file frogindexmodel.fn is an <b>R</b> script containing the commands for fitting multinomial mixture models. Some familiarity with <b>R</b> or the S language is assumed. As an illustration, the model contained in the first row of Table 2 of Royle and Link is fitted and the resulting output is returned. <br>
<br>
The remaining two objects are data matrices -- gf.data contains the Greenfrog calling index data. This is a matrix where rows index sample locations and columns index sample occasions. Missing values are indicated by "NA" <br>
The file gf.temp contains the temperature covariate data, in the same matrix format [sites × occasions]. </p>
