[R] graph results of logistic regression

I would like to graphically represent the results from a matched-pairs logistic regression. I am looking to represent each variable seperately in a graph, displaying the probability of selection for each. My study is looking at habitat selection in turtles so I am comparing habitat variables to turtle locations compared to paired random points
(differences in habitat).

Consulting previous questions in R help archives I found a somewhat similar request in september of 2005.
A response suggested some representation ideas using R code in a Bulletin of the ESA
<http://www.esapubs.org/bulletin/backissues/086-1/bulletinjan2005.htm#et>
(with a correction included in Erratum from volume 86(2)
http://www.esapubs.org/bulletin/backissues/086-2/et_bulletin86_2print.pdf As explained the code only tries to “efficiently” represent raw data in the traditional logistic plot that most ecologist are familiar with. However the code which is plot.logi.hist is not recognized when I tried and I could not find it in any of the packages. I am wondering how to run this code (ie- which package it might be in).

Any help would be greatly appreciated.
