R help - Sep 2008 - How to replicate probit regression analysis done by the priprobit software using R?

I wonder if anyone is familiar with the priprobit software (Sakuma M.
1998. Probit analysis of preference data. Appl Entomol Zool.
33:339?34). I would like to replicate the same analysis and output in
R. Of note, I want to determine the analytical sensitivity, defined as
95% cut-off value.
